Check Digit Verification of cas no

The CAS Registry Mumber 204651-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,6,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 204651-50:
(8*2)+(7*0)+(6*4)+(5*6)+(4*5)+(3*1)+(2*5)+(1*0)=103
103 % 10 = 3
So 204651-50-3 is a valid CAS Registry Number.

Domino Cu-catalyzed C-N coupling/hydroamidation: A highly efficient synthesis of nitrogen heterocycles

Martin, Ruben,Rivero, Marta Rodriguez,Buchwald, Stephen L.

, p. 7079 - 7082 (2007/10/03)

(Chemical Equation Presented) Working in tandem: Highly functionalized pyrroles and pyrazoles can be synthesized from a domino Cu-catalyzed C-N coupling/hydroamidation sequence. The scope and the generality of the method is noteworthy as a wide variety of substituents, either in the alkene or alkyne counterparts, are well tolerated.
