189331-46-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189331-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,3 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189331-46:
(8*1)+(7*8)+(6*9)+(5*3)+(4*3)+(3*1)+(2*4)+(1*6)=162
162 % 10 = 2
So 189331-46-2 is a valid CAS Registry Number.

Photoinduced and Palladium-Catalyzed Remote Desaturation of Amide Derivatives

Jin, Weiwei,Yu, Shouyun

, p. 6931 - 6935 (2021/09/11)

A photoinduced and palladium-catalyzed remote desaturation of O-acyl hydroxamides to unsaturated amides under mild conditions has been achieved. The formation of the alkyl Pd(II) intermediate by the recombination of alkyl radical and Pd(I) species is critical to achieve this efficient and selective desaturation of alkanes. This reaction features good site-selectivity, is terminal oxidant-free, and produces moderate to excellent yields for a variety of unsaturated amides. Remarkably, this approach enables late-stage desaturation of complex and biologically important molecules.
