Check Digit Verification of cas no

The CAS Registry Mumber 99472-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99472-74:
(7*9)+(6*9)+(5*4)+(4*7)+(3*2)+(2*7)+(1*4)=189
189 % 10 = 9
So 99472-74-9 is a valid CAS Registry Number.

Synthesis of indolo [1,2-a ]quinoxalines via a Pd-catalyzed regioselective C - H olefination/cyclization sequence

Wang, Liang,Guo, Wei,Zhang, Xiao-Xiao,Xia, Xu-Dong,Xiao, Wen-Jing

supporting information; experimental part, p. 740 - 743 (2012/04/10)

A highly efficient approach to indolo [1,2-a]quinoxaline derivatives through a Pd-catalyzed regioselective C - H olefination/cyclization sequence has been developed. This transformation has a wide range of substrates with various functional groups, and th
