Check Digit Verification of cas no

The CAS Registry Mumber 1269616-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,6,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1269616-09:
(9*1)+(8*2)+(7*6)+(6*9)+(5*6)+(4*1)+(3*6)+(2*0)+(1*9)=182
182 % 10 = 2
So 1269616-09-2 is a valid CAS Registry Number.

One-pot synthesis of triazolothiadiazepine 1,1-dioxide derivatives via copper-catalyzed tandem [3+2] cycloaddition/N-arylation

Barange, Deepak Kumar,Tu, Yu-Chen,Kavala, Veerababurao,Kuo, Chun-Wei,Yao, Ching-Fa

supporting information; experimental part, p. 41 - 48 (2011/03/22)

A practical and efficient synthesis of triazolothiadiazepine-1,1-dioxide derivatives via copper-catalyzed [3+2]cycloaddition, followed by N-arylation is described. The method is also applicable to the synthesis of indoline- and thiophene-fused triazolothiadiazepine 1,1-dioxide derivatives.
