Check Digit Verification of cas no

The CAS Registry Mumber 50361-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50361-97:
(7*5)+(6*0)+(5*3)+(4*6)+(3*1)+(2*9)+(1*7)=102
102 % 10 = 2
So 50361-97-2 is a valid CAS Registry Number.

Nickel-Catalyzed Claisen Condensation Reaction between Two Different Amides

Chen, Jiajia,Xu, Man,Yu, Subeen,Xia, Yuanzhi,Lee, Sunwoo

, p. 2287 - 2292 (2020)

A nickel-catalyzed Claisen condensation reaction between two amides, where one possesses an α-proton, for the synthesis of β-ketoamides was developed. Ni(glyme)Cl2 and terpyridine serve as the active catalysts in the presence of Mn and LiCl. N,N-Methylphenyl and N,N-diphenyl benzamide derivatives react with cyclic and noncyclic amides to give their corresponding β-ketoamides in moderate to good yields. In addition, a DFT calculation suggests that reductive elimination is the rate-determining step.
