Check Digit Verification of cas no

The CAS Registry Mumber 1388136-11-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,8,1,3 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1388136-11:
(9*1)+(8*3)+(7*8)+(6*8)+(5*1)+(4*3)+(3*6)+(2*1)+(1*1)=175
175 % 10 = 5
So 1388136-11-5 is a valid CAS Registry Number.

Synthesis of15N-labeled heterocyclesviathe cleavage of C-N bonds of anilines and glycine-15N

He, Jiwen,Zhang, Xingguo,He, Qiuqin,Guo, Hao,Fan, Renhua

, p. 5442 - 5445 (2021)

A nitrogen replacement process that directly incorporates the15N atom of glycine-15N into anilines was reported. The process involves a Csp2-N bond cleavage of anilines driven by dearomatization and a Csp3-N bond cleavage of glycine-15N driven by aromatization. A variety of15N-labeled aromatic heterocycles can be preparedviathis process.
