21856-53-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21856-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21856-53:
(7*2)+(6*1)+(5*8)+(4*5)+(3*6)+(2*5)+(1*3)=111
111 % 10 = 1
So 21856-53-1 is a valid CAS Registry Number.

Palladium-Catalyzed Atom-Transfer Radical Cyclization at Remote Unactivated C(sp3)?H Sites: Hydrogen-Atom Transfer of Hybrid Vinyl Palladium Radical Intermediates

Ratushnyy, Maxim,Parasram, Marvin,Wang, Yang,Gevorgyan, Vladimir

supporting information, p. 2712 - 2715 (2018/03/02)

A novel mild, visible-light-induced palladium-catalyzed hydrogen atom translocation/atom-transfer radical cyclization (HAT/ATRC) cascade has been developed. This protocol involves a 1,5-HAT process of previously unknown hybrid vinyl palladium radical intermediates, thus leading to iodomethyl carbo- and heterocyclic structures.
