55022-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55022-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,2 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55022-46:
(7*5)+(6*5)+(5*0)+(4*2)+(3*2)+(2*4)+(1*6)=93
93 % 10 = 3
So 55022-46-3 is a valid CAS Registry Number.

5-exo atom transfer cyclisation onto alkynes mediated by copper(I) complexes

Clark, Andrew J.,Battle, Gary M.,Bridge, Andrew

, p. 1999 - 2001 (2001)

Multidentate amine derived copper(I) halide complexes mediate the atom transfer radical cyclisation of 1-halo-N-propargylacetamides. While cyclisation of trichloro- and dichloroacetamide derivatives leads to α,β-unsaturated γ-lactams containing the gem-dihalide functional group, monohaloacetamides give rise to either cyclised atom transfer or reduction products depending upon the solvent and catalyst used.

Pd-Catalyzed Cascade Metallo-Ene Cyclization/Metallo-Carbene Coupling of Allenamides

Cao, Chengqiang,Yang, Yi,Li, Xin,Liu, Yunxia,Liu, Hui,Zhao, Zengdian,Chen, Lei

supporting information, p. 1538 - 1542 (2021/03/01)

A highly efficient palladium-catalyzed cascade metallo-ene/metallo-carbene coupling reaction was developed to produce 2,3-dihydropyrrole derivatives in high yields. In this transformation, two new Csp3?Csp2 and Csp2?Cspsu

Photoinduced Phosphorylation/Cyclization of Cyanoaromatics for Divergent Access to Mono- And Diphosphorylated Polyheterocycles

Shi, Shanshan,Zheng, Zhipeng,Zhang, Yumeng,Yang, Yufei,Ma, Denghui,Gao, Yuzhen,Liu, Yan,Tang, Guo,Zhao, Yufen

supporting information, p. 9348 - 9352 (2021/12/14)

The visible-light-driven switchable phosphorylation of cyanoaromatics with the 1,6-enyne moiety for the diverse and selective synthesis of phosphorylated polyheterocycles, including phosphorylated aminophosphonates, iminophosphonates, and ketones, has bee
