Check Digit Verification of cas no

The CAS Registry Mumber 149691-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,6,9 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149691-67:
(8*1)+(7*4)+(6*9)+(5*6)+(4*9)+(3*1)+(2*6)+(1*7)=178
178 % 10 = 8
So 149691-67-8 is a valid CAS Registry Number.

Preparation of chiral 3-arylpyrrolidines via the enantioselective 1,4-addition of arylboronic acids to fumaric esters catalyzed by Rh(I)/chiral diene complexes

Chung, Yu-Chiang,Janmanchi, Damodar,Wu, Hsyueh-Liang

, p. 2766 - 2769 (2012/07/17)

A highly efficient rhodium-catalyzed protocol for the preparation of 2-arylsuccinic esters and 3-arylpyrrolidines of high optical purity has been achieved. In the presence of 1 mol % of a chiral diene/Rh(I) catalyst, asymmetric addition of various arylbor
