Check Digit Verification of cas no

The CAS Registry Mumber 1379793-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,9,7,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1379793-81:
(9*1)+(8*3)+(7*7)+(6*9)+(5*7)+(4*9)+(3*3)+(2*8)+(1*1)=233
233 % 10 = 3
So 1379793-81-3 is a valid CAS Registry Number.

Synthesis of 1,1-diarylethylenes via efficient iron/copper Co-catalyzed coupling of 1-arylvinyl halides with Grignard reagents

Hamze, Abdallah,Brion, Jean-Daniel,Alami, Mouad

, p. 2782 - 2785 (2012/07/14)

An efficient access to 1,1-diarylethylenes of biological interest by coupling functionalized aryl Grignard reagents and 1-arylvinyl halides in the presence of FeCl3/CuTC is described. This bimetallic system proved to be superior to the use of Fe or Cu catalyst alone. The synthetic utility of this protocol is illustrated in the field of steroid chemistry.
