Check Digit Verification of cas no

The CAS Registry Mumber 1096357-17-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,6,3,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1096357-17:
(9*1)+(8*0)+(7*9)+(6*6)+(5*3)+(4*5)+(3*7)+(2*1)+(1*7)=173
173 % 10 = 3
So 1096357-17-3 is a valid CAS Registry Number.

Synthesis of benzimidazoles from 1,1-dibromoethenes

Shen, Wang,Kohn, Todd,Fu, Zice,Jiao, XianYun,Lai, Sujen,Schmitt, Michael

, p. 7284 - 7286 (2008)

A mild and efficient method for the preparation of substituted benzimidazoles from 1,1-dibromoethenes and o-diaminobenzenes is described. The reaction employs DABCO as the base and NMP as the solvent. A variety of substitutions on both 2-aryl-1,1-dibromoethenes and o-diaminobenzenes are tolerated. This new procedure is carried out under mildly basic conditions, which may provide a complementary route to the existing preparations of benzimidazoles.
