Check Digit Verification of cas no

The CAS Registry Mumber 21639-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21639-15:
(7*2)+(6*1)+(5*6)+(4*3)+(3*9)+(2*1)+(1*5)=96
96 % 10 = 6
So 21639-15-6 is a valid CAS Registry Number.

Copper-Catalyzed Synthesis of 1,2,4-Benzothiadiazine 1,1-Dioxide Derivatives by coupling of 2-Halobenzenesulfonamides with amidines

Yang, Daoshan,Liu, Hongxia,Yang, Haijun,Fu, Hua,Hu, Liming,Jiang, Yuyang,Zhao, Yufen

, p. 1999 - 2004 (2009)

We have developed a simple and practical copper-catalyzed method for the synthesis of 1,2,4-benzothiadiazine 1,1-dioxide derivatives via cascade reactions of substituted 2-halobenzenesulfonamides with amidines, and the method is of value for the construction of this kind of molecules with biological and medicinal activities.
