Check Digit Verification of cas no

The CAS Registry Mumber 1632197-34-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,1,9 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1632197-34:
(9*1)+(8*6)+(7*3)+(6*2)+(5*1)+(4*9)+(3*7)+(2*3)+(1*4)=162
162 % 10 = 2
So 1632197-34-2 is a valid CAS Registry Number.

An efficient and facile synthesis of benzimidazo[1,2-a]benzimidazoles via copper-catalyzed domino addition/double cyclization

Yuan, Guodong,Liu, Haiquan,Gao, Jilong,Xu, Hongjuan,Jiang, Liu,Wang, Xiaoxia,Lv, Xin

, p. 21904 - 21908 (2014)

A copper-catalyzed synthesis of benzimidazo[1,2-a]benzimidazoles by domino addition/double cyclization of bis-(o-haloaryl)carbodiimides with primary amines was developed. A variety of the desired polycyclic benzimidazoles were efficiently and facilely assembled. Multibonds and polycyclic moieties were directly constructed in one pot. 2-Bromo-2′-iodo-diarylcarbodiimides gave good selectivity. This journal is the Partner Organisations 2014.
