Check Digit Verification of cas no

The CAS Registry Mumber 77198-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77198-54:
(7*7)+(6*7)+(5*1)+(4*9)+(3*8)+(2*5)+(1*4)=170
170 % 10 = 0
So 77198-54-0 is a valid CAS Registry Number.

Shaterian, Hamid Reza,Honarmand, Moones,Oveisi, Ali Reza

, p. 557 - 560 (2010)

A facile parallel synthesis of 3,5-diaryl-2,6-dicyanoanilines via three-component reaction of aryl aldehydes, acetophenone derivatives, and malononitrile under thermal green solvent-free conditions in the presence of potassium carbonate and also potassium bicarbonate without using any hazardous materials is described.
