Check Digit Verification of cas no

The CAS Registry Mumber 2618-96-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2618-96:
(6*2)+(5*6)+(4*1)+(3*8)+(2*9)+(1*6)=94
94 % 10 = 4
So 2618-96-4 is a valid CAS Registry Number.

Merging Photoredox Catalysis with Transition Metal Catalysis: Direct C4-H Sulfamidation of 1-Naphthylamine Derivatives

, p. 11324 - 11332 (2021/09/02)

A mild and efficient protocol for the copper(I)-catalyzed C4-H sulfamidation of 1-naphthylamine derivatives with diphenylsulfonimide (NHSI) was explored at room temperature, affording the desire produces in moderate to good yields. The control experiments indicated that this visible-light-promoted reaction might proceed via a single-electron-transfer process. In addition, preliminary DFT studies for the intermediates in the catalytic cycle were also explored, indicating that the C4 site in the naphthyl ring is the most likely electrophilic reactive site and providing some exact basis for the plausible mechanism.

Copper-Catalyzed Radical N-Demethylation of Amides Using N-Fluorobenzenesulfonimide as an Oxidant

An unprecedented N-demethylation of N-methyl amides has been developed by use of N-fluorobenzenesulfonimide as an oxidant with the aid of a copper catalyst. The conversion of amides to carbinolamines involves successive single-electron transfer, hydrogen-atom transfer, and hydrolysis, and is accompanied by formation of N-(phenylsulfonyl)benzenesulfonamide. Carbinolamines spontaneously decompose to N-demethylated amides and formaldehyde, because of their inherent instability.

The invention relates to a method for preparing dibenzenesulfonimide by a solvent-free grinding method. According to the method, firstly, benzsulfamide and pure benzene sulfonyl chloride are put into a ball mill to be ground, so that the benzsulfamide and the benzene sulfonyl chloride are sufficiently and uniformly mixed at room temperature; then, solid NaOH is fed into the ball mill in different batches; the grinding is continuously performed; the temperature of a reactant is maintained to be lower than 60 DEG C; after the reaction is completed, the reactant is moved out from the ball mill; the reactants are dissolved by organic solvents; filtering is performed for removing generated NaCl; filter liquid is obtained; finally, the filter liquid is subjected to concentration crystallization, filtering and drying; a product is obtained. In the whole reaction process, the solvent is not needed; the environment pollution is reduced; the production cost is reduced. The atom utilization rate of the whole preparation process is high; the atom economic green and environment-friendly ideal is met; the method is suitable for industrial production.
