Check Digit Verification of cas no

The CAS Registry Mumber 1388136-05-7 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, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1388136-05:
(9*1)+(8*3)+(7*8)+(6*8)+(5*1)+(4*3)+(3*6)+(2*0)+(1*5)=177
177 % 10 = 7
So 1388136-05-7 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

supporting information, p. 5442 - 5445 (2021/06/09)

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.

Visible-Light-Mediated [2+2+1] Carbocyclization Reactions of 1,7-Enynes with Bromofluoroacetate to Form Fused Monofluorinated Cyclopenta[ c]quinolin-4-ones

Li, Yongqiang,Liu, Yuxiu,Qu, Yi,Song, Hongjian,Wang, Qingmin,Xu, Wentao,Zhang, Jingjing

, p. 5379 - 5389 (2020/05/19)

Herein, we describe a new protocol for photoinduced radical [2+2+1] carbocyclization reactions of 1,7-enynes with bromofluoroacetate. These reactions, which proceed via a cascade involving fluoroalkylation, 6-exo-dig and 5-endo-trig cyclizations, H-transf
