Check Digit Verification of cas no

The CAS Registry Mumber 1337913-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,9,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1337913-23:
(9*1)+(8*3)+(7*3)+(6*7)+(5*9)+(4*1)+(3*3)+(2*2)+(1*3)=161
161 % 10 = 1
So 1337913-23-1 is a valid CAS Registry Number.

Ligand-free iron-catalyzed benzylic C (sp3)-H amination of methylarenes with: N -fluorobenzenesulfonimide

Bao, Fengyu,Cao, Yuanbo,Liu, Wenbo,Zhu, Junhao

, p. 27892 - 27895 (2019/09/30)

Direct conversion of cheap methylarenes to benzylic amines, which are essential structural units of important drugs, is of great significance. However, the known methodologies suffer from the requirement of noble metal catalysts, heavy metal residues or s

Copper(i)-catalyzed radical decarboxylative imidation of carboxylic acids with N-fluoroarylsulfonimides

Fang, Zhongxue,Feng, Yu,Dong, Hai,Li, Dashan,Tang, Tiandi

supporting information, p. 11120 - 11123 (2016/09/19)

An efficient copper-catalyzed radical decarboxylative imidation reaction is presented. This strategy is carried out through the copper(i)-catalyzed decarboxylative C(sp3)-N and C(sp2)-N coupling of carboxylic acids with N-fluoroarylsulfonimides. The reaction shows good functional group tolerance and it provides a new approach for decarboxylative imidation. Preliminary mechanistic studies of this transformation suggest an involvement of N-centered radical species.

Intermolecular oxidative C-N bond formation under metal-free conditions: Control of chemoselectivity between aryl sp2 and benzylic sp 3 C-H bond imidation

Kim, Hyun Jin,Kim, Jiyu,Cho, Seung Hwan,Chang, Sukbok

supporting information; experimental part, p. 16382 - 16385 (2011/12/13)

A new synthetic approach toward intermolecular oxidative C-N bond formation of arenes has been developed under transition-metal-free conditions. Complete control of chemoselectivity between aryl sp2 and benzylic sp 3 C-H bond imidation was achieved by the choice of nitrogen sources, representatively being phthalimide and dibenzenesulfonimide, respectively.
