Check Digit Verification of cas no

The CAS Registry Mumber 1221497-76-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,9 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1221497-76:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*9)+(3*7)+(2*7)+(1*6)=142
142 % 10 = 2
So 1221497-76-2 is a valid CAS Registry Number.

Tandem reactions of N′-(2-Alkynylbenzylidene)hydrazides with Silyl Enolates: A facile route to H -pyrazolo[5,1- a ]isoquinolines

Yu, Xingxin,Chen, Zhiyuan,Yang, Xiaodi,Wu, Jie

experimental part, p. 374 - 378 (2010/09/11)

A silver triflate-catalyzed tandem reaction of N′-(2- alkynylbenzylidene)hydrazide with silyl enolate is described, which generates the unexpected H-pyrazolo[5,1-a]isoquinolines in good to excellent yields. Intramolecular cyclization, nucleophilic addition, condensation, and aromatization may be involved in the reaction process.
