Check Digit Verification of cas no

The CAS Registry Mumber 136397-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,9 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136397-28:
(8*1)+(7*3)+(6*6)+(5*3)+(4*9)+(3*7)+(2*2)+(1*8)=149
149 % 10 = 9
So 136397-28-9 is a valid CAS Registry Number.

NOVEL 4,5-DIHYDROPYRAZOLOPYRIMIDIN-4-ONES AND 3,4-DIHYDROPYRAZOLO-1,2,3-TRIAZIN-4-ONES

Maquestiau, A.,Banneux, F.,Eynde, J.-J. Vanden

, p. 401 - 406 (2007/10/02)

β-benzylidene 3- and 5-amino-1-methyl-1H-pyrazole-4-carboxhydrazides 3 and 4 readily react with orthoesters to yield the 4,5-dihydropyrazolopyrimidin-4-ones 5-8.Syntheses of 3,4-dihydropyrazolo-1,2,3-triazin-4-ones 9, 10, 13 and 14 were achi
