Check Digit Verification of cas no

The CAS Registry Mumber 1213779-81-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,7,7 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1213779-81:
(9*1)+(8*2)+(7*1)+(6*3)+(5*7)+(4*7)+(3*9)+(2*8)+(1*1)=157
157 % 10 = 7
So 1213779-81-7 is a valid CAS Registry Number.

Synthesis of 2,3-diarylbenzo[b]thiophenes via nickel-catalyzed suzuki-miyaura cross-coupling and palladium-catalyzed decarboxylative arylation

Miyasaka, Mitsuru,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

scheme or table, p. 2683 - 2688 (2009/12/30)

We report a new approach to 2,3-diaryl-benzo[D]thiophenes based on the nickel-catalyzed Suzuki-Miyaura cross-coupling/palladium-catalyzed decarboxylative arylation sequence of 3-chloro-2-me-thoxycarbonylbenzo[D] thiophenes, which are readily accessible fr
