Check Digit Verification of cas no

The CAS Registry Mumber 112055-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,5 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112055-57:
(8*1)+(7*1)+(6*2)+(5*0)+(4*5)+(3*5)+(2*5)+(1*7)=79
79 % 10 = 9
So 112055-57-9 is a valid CAS Registry Number.

Aza-Michael addition of acrylonitrile with 2-aryloxymethylbenzimidazole derivatives under microwave irradiation

Wei, Tai-Bao,Hua, Mao-Tang,Shi, Hai-Xiong,Liu, Yong,Zhang, You-Ming

experimental part, p. 452 - 454 (2010/12/24)

A simple, rapid, and highly efficient method has been developed for the aza-Michael addition of acrylonitrile to 2-aryl-oxymethylbenzimidazole derivatives in the presence of anhydrous potassium carbonate under microwave irradiation. A series novel of 1-cyanoethyl-2-aryloxymethylbenzimidazole derivatives have been prepared and characterised by 1H NMR, 13C NMR, IR spectra and elemental analysis.
