1,6-diiodohexane

Hi,

I found for the page fr:1,6-Diiodohexane, CAS#629-09-4 that all ref used but on lookchem (spam blacklisted).com/Molecular-Formula/C6H12I2.html, I found too CAS#55290-40-9 for this compound that I don't see elsewhere. What is this CAS number ? is it wrong ? thank you for you help --Titou (talk) 07:13, 1 October 2016 (UTC)

@The Titou: 629-09-4 is 1,6-diiodohexane and 55290-40-9 is diiodohexane with unspecified substitution. -- Ed (Edgar181) 12:20, 3 October 2016 (UTC)
Okay ! thanks a lot --Titou (talk) 08:25, 4 October 2016 (UTC)

Akaki Tsilosani

Prof. Akaki Tsilosani is a prominent transplant surgeon, founder of TALIZI Clinic. He is recognized worldwide as one of the leading surgeons. Member and expert of International Society of Hair Restoration Surgery (ISHRS). There surely should be an article about A. Tsilosani in English Wikipedia too.

If an article needs some modification please let me know exactly what to do. I contribute to Wikipedia almost 10 years and I've read policies and want to modify this article so that it will be approved. Based on international recognition among colleagues and significant contribution to hair transplant surgery development, this article meets all Wikipedia criteria. I'm sure afer re editing and correction this article will be restored. Please advice exactly how to modify the article. Thank you in advance! Zetalion (talk) 2 November 2016

The article Akaki Tsilosani was deleted by the administrator User:Deb. The reason she gave was, "Unambiguous advertising or promotion". I only deleted the talk page Talk:Akaki Tsilosani which was orphaned by the article deletion. If you have questions about the article deletion, it would be best to contact User:Deb. Regards, -- Ed (Edgar181) 18:33, 6 October 2016 (UTC)
Thanks. This contributor has already been to my talk page, but presumably thinks he will get a different answer if he asks someone else. As yet he hasn't taken my advice to re-read the guidelines and go to the Teahouse in case of doubt. Deb (talk) 19:10, 6 October 2016 (UTC)

CAS numbers, Always CAS numbers

Hi Edgar,
How are you ? For my part, I can't find the CAS numbers of a pair of enantiomers C6H12, namely :

  • 3-méthylpent-1-ène, numéro CAS 760-20-3 , racemate
    • (3R)-3-méthylpent-1-ène, numéro CAS ?
    • (3S)-3-méthylpent-1-ène, numéro CAS ?

Could you help me, please, as usual ^^ (i.e. with too ± descriptors, if possible) - Have a good day --Titou (talk) 05:31, 14 October 2016 (UTC)

Here it is:
(R)-3-methyl-1-pentene 39914-58-4
(S)-3-methyl-1-pentene 5026-95-9
-- Ed (Edgar181) 12:14, 14 October 2016 (UTC)
Super! Merci bcp! --Titou (talk) 12:21, 15 October 2016 (UTC)

Propellanes and a new C6H6 isomer!

May be very more difficult to find, could you see if CAS number exists for the following compounds :

  • the propellanes which appear in the article :
    • [1.1.1]propellane or tricyclo[1.1.1.01,3]pentane
    • [2.1.1]propellane or tricyclo[2.1.1.01,4]hexane
    • [2.2.1]propellane or tricyclo[2.2.1.01,4]heptane
    • [2.2.2]propellane or tricyclo[2.2.2.01,4]octane
    • [3.1.1]propellane or tricyclo[3.1.1.01,5]heptane
    • [3.2.1]propellane or tricyclo[3.2.1.01,5]octane
    • [4.1.1]propellane or tricyclo[4.1.1.01,6]octane
    • [3.3.3]propellane or tricyclo[3.3.3.01,5]undecane
    • [4.3.3]propellane or tricyclo[4.3.3.01,6]dodecane
    • [6.3.3]propellane or tricyclo[6.3.3.01,8]tetradecane
    • [10.3.3]propellane or tricyclo[10.3.3.01,12]octadecane
  • In the ref of this article, I find : Ursula Szeimies-Seebach, Joachim Harnish, Günter Szeimies, Maurice Van Meerssche, Gabriel Germain, Jean-Paul Declerq, Existence of a New C6H6 Isomer: Tricyclo[3.1.0.02,6]hex-1(6)-ene, Angew. Chem. Int. Ed. Engl., 1978, vol. 17(11), pp. 848–850. doi:10.1002/anie.197808481. So CAS number for
    • Tricyclo[3.1.0.02,6]hex-1(6)-ene, CAS number ?
  • Finally, for good measure, I forgot in C6H12, stereoisomers of 1,1,2-trimethylcyclopropane, CAS number 4127-45-1
    • cis-1,1,2-trimethylcyclopropane, CAS number ?
    • trans-1,1,2-trimethylcyclopropane, CAS number ? and correspondance between cis/trans and R/S descriptors for this pair

Whaou, if you can find all of them, you will be like the good of CAS number Face-smile.svg --Titou (talk) 12:21, 15 October 2016 (UTC)

I'll look these up on Monday. -- Ed (Edgar181) 21:35, 15 October 2016 (UTC)
@The Titou: Here is what I have found. -- Ed (Edgar181) 15:04, 17 October 2016 (UTC)
[1.1.1]Propellane: 35634-10-7
[2.1.1]propellane: 36120-91-9
[2.2.1]Propellane: 36120-90-8
[2.2.2]propellane: 36120-88-4
[3.1.1]propellane: 65513-21-5
[3.2.1]propellane: 19074-25-0
[4.1.1]propellane: 51273-56-4
[3.3.3]propellane: 51027-89-5
[4.3.3]Propellane: 7161-28-6
[6.3.3]propellane: 67140-86-7
[10.3.3]propellane: 58602-52-1
Tricyclo[3.1.0.02,6]hex-1(6)-ene: 68108-93-0
1,1,2-trimethylcyclopropane does not have cis- and trans-disastereomers, only (R)- and (S)- enantiomers. Chemical Abstracts does not appear to have CAS numbers for the individual enantiomers.
Thanks a lot ! incredible you find all this CAS numbers - it's marvelous. I don't understand why enantiomers of 1,1,2-trimethylcyclopropane haven't CAS number while stereoisomers of 1-méthyl-2-éthylcyclopropane have (19781-68-1 cis, 19781-69-2 trans) and those of 1,2,3-triméthylcyclopropane too (4806-59-1 r-1,c-2,t-3- , 4806-58-0 r-1,c-2,c-3-)... bizarre = strange...
Really thank you very much for your help! regards --Titou (talk) 18:33, 17 October 2016 (UTC)

Thanks

Hello E. Thanks for your quick actions in dealing with the troll (ips and named users) who is messing around. In case you haven't seen it yet this unblock request is kind of funny - like a block at WikiP keeps people off the net entirely. Hmmmm might be worth requesting this feature at VPT :-) Enjoy the rest of your weekend. MarnetteD|Talk 21:33, 15 October 2016 (UTC)

You're welcome. I'm glad to help. -- Ed (Edgar181) 21:34, 15 October 2016 (UTC)

spamblacklistblock

Hi Edgar, I have taken the freedom to re-block 95.79.200.177 using {{spamblacklistblock}} as reason (it is available in Twinkle). As this one, for these IPs one also needs to withdraw talkpage access. As can be seen from Special:Log/spamblacklist/95.79.200.177, half of their edits are attempts to spam on their own talkpages, and they keep obscuring the log with that (see these 500 attempts). Cheers. --Dirk Beetstra T C 12:13, 16 October 2016 (UTC)

Thanks. I hadn't noticed that spamblacklistblock was one of the default block options. I'll be sure to use it in the future and to remove talk page access. Regards, -- Ed (Edgar181) 12:16, 16 October 2016 (UTC)

C6H6 isomers

Hi,

Yesterday, you give the CAS number for (2s,5s)-tricyclo[3.1.0.02,6]hex-1(6)-ene 68108-93-0 and benzvalene or (1s,2r,5r,6s)-tricyclo[3.1.0.02,6]hex-3-ene have too one, 659-85-8 . I think may be "they" give too CAS number to other isomers of tricyclo[3.1.0.02,6]hexene. So I chek those with ChemSketch and finally I found :

Please, could you see if the three missing CAS numbers exist for those isomers, may be not still synthetized.... thank you for your help --Titou (talk) 10:37, 18 October 2016 (UTC)

Sorry, I am unable to find CAS numbers for those compounds. -- Ed (Edgar181) 12:17, 18 October 2016 (UTC)
Does it that means those CAS numbers don't exist?? --Titou (talk) 19:11, 19 October 2016 (UTC)
Normally, I would be confident that if I can't find a CAS number by searching Chemical Abstracts then that number doesn't exist. But in this case, the names and chemical structures are complicated enough that I may have missed something - I can't be 100% sure. -- Ed (Edgar181) 19:32, 19 October 2016 (UTC)

File:Acetyldigoxin.png

Hi Ed. This structure shows in fact α-acetyldigoxin, right? What about moving Acetyldigoxin since there is also β-acetyldigoxin? --Leyo 09:03, 28 October 2016 (UTC)

I think only one article is needed - just one to cover the isomer that is used in medicine. But after a quick Google search, I can't determine which isomer it is. Do you know? I can create an image for the β isomer if needed. -- Ed (Edgar181) 12:21, 28 October 2016 (UTC)
AFAIK the difference is the location of the acetyl group (α, β). There is an image of the β isomer in de:β-Acetyldigoxin. --Leyo 21:08, 28 October 2016 (UTC)
It looks like the English article should be about β isomer too. I'll translate the German article and switch the infobox to match that isomer. -- Ed (Edgar181) 13:15, 29 October 2016 (UTC)
If you do so, please adapt d:Q4673300 and d:Q18030160 accordingly. --Leyo 22:10, 30 October 2016 (UTC)
