Check Digit Verification of cas no

The CAS Registry Mumber 862898-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,8,9 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 862898-37:
(8*8)+(7*6)+(6*2)+(5*8)+(4*9)+(3*8)+(2*3)+(1*7)=231
231 % 10 = 1
So 862898-37-1 is a valid CAS Registry Number.

Conversion of sterically hindered diacylated 1,2-phenylenediamines into 2-substituted benzimidazoles

Charton, Julie,Girault-Mizzi, Sophie,Sergheraert, Christian

, p. 492 - 497 (2007/10/03)

A series of bulky 2-substituted benzimidazoles was designed in order to find new leads for several biological targets. Formation by cyclodehydration from their monoacylated counterparts was shown to be strongly dependent upon the nature of the acyl group. In the case of a dicyclohexylmethyl group, cycllzation was only observed in a p-toluenesulfonic acid/toluene mixture from the symmetrical diacylated precursor. Analysis of the mechanism was begun starting from mixed diacylated derivatives.
