Check Digit Verification of cas no

The CAS Registry Mumber 51003-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51003-31:
(7*5)+(6*1)+(5*0)+(4*0)+(3*3)+(2*3)+(1*1)=57
57 % 10 = 7
So 51003-31-7 is a valid CAS Registry Number.

Assembly of Polysubstituted Maleimides via Palladium-Catalyzed Cyclization Reaction of Alkynes with Isocyanides

Hu, Weigao,Zheng, Jia,Li, Jianxiao,Liu, Bifu,Wu, Wanqing,Liu, Haiyang,Jiang, Huanfeng

, p. 12451 - 12458 (2016)

An efficient and convenient palladium-catalyzed cyclization reaction of alkynes with isocyanides is described herein. This protocol allows the practical synthesis of many valuable polysubstituted maleimide derivatives after hydrolysis with a broad scope of substrates and mild reaction conditions. C-C, CO, and C-N bonds were constructed in this transformation with isocyanide serving as both C and N sources.
