Check Digit Verification of cas no

The CAS Registry Mumber 142267-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,6 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142267-23:
(8*1)+(7*4)+(6*2)+(5*2)+(4*6)+(3*7)+(2*2)+(1*3)=110
110 % 10 = 0
So 142267-23-0 is a valid CAS Registry Number.

, p. 1125 - 1129 (1991)

Cyclization of 2-(N-acetyl-N-arylamino)nicotinonitriles in the presence of dry HCl gave 1-aryl-2-methyl-4-oxo-1,4-dihydropyridopyrimidines.It was shown that they are acylated by acetic anhydride, aroyl chlorides, and phenyl isocyanate at the methyl
