Check Digit Verification of cas no

The CAS Registry Mumber 1189142-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,4 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1189142-24:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*4)+(3*2)+(2*2)+(1*4)=162
162 % 10 = 2
So 1189142-24-2 is a valid CAS Registry Number.

α-aminoazoles in the Synthesis of heterocycles: V. Synthesis of azolo[1,5-a]pyrimidines from 2-ethoxyvinyl trifluoromethyl ketones and 2,2-diethoxyvinyl trifluoromethyl ketone

Emelina,Petrov

, p. 417 - 420 (2009)

A procedure was proposed for the synthesis of 7-trifluoromethylazolo[1,5-a] pyrimidines by reactions of 2-ethoxyvinyl trifluoromethyl ketones and 2,2-diethoxyvinyl trifluoromethyl ketone with 5(3)-aminoazoles. The reactions occurred under mild conditions,
