Check Digit Verification of cas no

The CAS Registry Mumber 176763-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,7,6 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 176763-62:
(8*1)+(7*7)+(6*6)+(5*7)+(4*6)+(3*3)+(2*6)+(1*2)=175
175 % 10 = 5
So 176763-62-5 is a valid CAS Registry Number.

Cobalt-Catalyzed Intermolecular Hydroamination of Unactivated Alkenes Using NFSI as Nitrogen Source

Li, Linshan,Li, Yuxin,Li, Zhengming,Sun, Peng-Wei,Wang, Xinyao,Zhang, Ze

, (2022/02/23)

Cheap metal (Fe, Mn, and Co)-catalyzed hydroamination of alkenes has been an attractive method for synthesis of amines because of biocompatibility of metal, excellent Markovnikov selectivity and chemoselectivity. However, most reports are limited to unsaturated nitrogen sources (nitric oxide, azos, azides, cyano, etc.), for which aminated products are very limited. Notably, while used widely for fluorinating reaction, N-fluorobenzenesulfonimide (NFSI) as amine source for hydroamination has seldom been reported. Here we developed a cobalt-catalyzed intermolecular hydroamination of unactivated alkenes using NFSI as nitrogen source under mild conditions. The reaction exhibits excellent chemo- and regio-selectivity with no hydrofluorination or linear-selectivity products. Notably, the reaction proceeded with excellent yield even though the amount of Co(salen) catalyst was reduced to 0.2 mol%. Recently, a similar work was also reported by Zhang and coworkers (ref. 19).

Switchable Polymerization Triggered by Fast and Quantitative Insertion of Carbon Monoxide into Cobalt–Oxygen Bonds

A strategy that uses carbon monoxide (CO) as a molecular trigger to switch the polymerization mechanism of a cobalt Salen complex [salen=(R,R)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine] from ring-opening copolymerization (ROCOP) of ep

Selective H2O2 oxidation of organic sulfides to sulfoxides catalyzed by cobalt(III)-salen ion

Mary Imelda Jayaseeli,Ramdass, Arumugam,Rajagopal, Seenivasan

, p. 59 - 66 (2015/08/11)

Abstract The catalytic activity of cobalt(III)-salen ion catalyzed selective H2O2 oxidation of organic sulfides to sulfoxides is examined using spectrophotometric technique. The catalytic reaction proceeds through Michaelis-Menten kinetics and the rate of the reaction is highly sensitive to the nature of the substituent present in the substrate as well as in the salen ligand. The product analyses show that the aryl methyl sulfides are selectively oxidized to the corresponding sulfoxides. Based on the spectral and kinetic studies two possible mechanisms have been proposed.
