1375004-99-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1375004-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,0,0 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1375004-99:
(9*1)+(8*3)+(7*7)+(6*5)+(5*0)+(4*0)+(3*4)+(2*9)+(1*9)=151
151 % 10 = 1
So 1375004-99-1 is a valid CAS Registry Number.

Syntheses of polyfunctionalized resveratrol derivatives using Wittig and Heck protocols

Chalal, Malik,Vervandier-Fasseur, Dominique,Meunier, Philippe,Cattey, Hélène,Hierso, Jean-Cyrille

, p. 3899 - 3907 (2012/07/14)

Improved protocols for Wittig reaction and palladium-catalyzed Heck coupling give expedient access to a series of unprecedented polyfunctionalized artificial-resveratrol derivatives. In the modified Wittig protocol, trimethylsilyl was used as a highly valuable protective group of the phenolic functions of starting aromatic materials. A clean O-alkylation of hydroxylated stilbenes with ethylene carbonate was also conducted. Thus, Wittig reaction followed by hydroxyethylation take place one-pot with only carbon dioxide as waste. Additionally, a palladium-catalyzed Heck coupling strategy was developed by using ferrocenyl phosphane ligands, and multi-functionalized hydroxylated stilbenes were obtained without the need of any protection/deprotection sequence. Up to six functional groups are introduced by these procedures, which limit the number of reactions steps, the waste toxicity, and the use of costly reagents.
