Check Digit Verification of cas no

The CAS Registry Mumber 1616512-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,5,1 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1616512-07:
(9*1)+(8*6)+(7*1)+(6*6)+(5*5)+(4*1)+(3*2)+(2*0)+(1*7)=142
142 % 10 = 2
So 1616512-07-2 is a valid CAS Registry Number.

Three-component synthesis of 4-aroyl-2(1),4,5,7-Tetrahydropyrazolo[3,4-b] Pyridin-6-ones and their properties

, p. 514 - 527 (2014/08/05)

Inspired by the concept of multicomponent reactions, a novel one-pot synthesis involving arylglyoxals, 5-aminopyrazoles, and Meldrum's acid has been developed and employed for the creation of a small library of 4-aroyl-2(1),4,5,7-tetrahydropyrazolo[3,4-b]pyridin-6-ones. The alkylation, acylation, reduction, and oxidation reactions of 4-aroyl-3-methyl-2,4,5,7- tetrahydropyrazolo[3,4-b]pyridin-6-ones have been studied.
