Check Digit Verification of cas no

The CAS Registry Mumber 1283231-56-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,2,3 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1283231-56:
(9*1)+(8*2)+(7*8)+(6*3)+(5*2)+(4*3)+(3*1)+(2*5)+(1*6)=140
140 % 10 = 0
So 1283231-56-0 is a valid CAS Registry Number.

Copper(ii)-catalyzed protoboration of allenes in aqueous media and open air

Nekvinda, Jan,Santos, Webster L.,Snead, Russell F.

, p. 14925 - 14931 (2021/09/04)

A method has been developed for the facile Cu(ii)-catalyzed protoboration of monosubstituted allenes in aqueous media under atmospheric conditions. The reaction occurs site selectively, favoring internal alkene protoboration to afford 1,1-disubstituted vinylboronic acid derivatives (up to 93?:?7) with modest to good yields. The method has been applied to a variety of phenylallene derivatives as well as alkyl-substituted allenes. This journal is

Rh-Catalyzed Asymmetric Hydrogenation of α,β- and β,β-Disubstituted Unsaturated Boronate Esters

Hou, Guohua,Shen, Xin,Yan, Qiaozhi,Zi, Guofu

supporting information, (2020/05/08)

A highly enantioselective hydrogenation of α,β-unsaturated boronate esters catalyzed by Rh-(S)-DTBM-Segphos complex has been developed. Both (Z)-α,β- and β,β-disubstituted substrates can be successfully hydrogenated to afford chiral boronates with excellent enantioselectivities, up to 98 % ee. Furthermore, the obtained chiral boronate esters, as important versatile synthetic intermediates are successfully transformed to the corresponding chiral alcohols, amines and other important derivatives with maintained enantioselectivities.

Spiro(phosphoamidite) ligand (SIPHOS)/Cu(OTf)2-catalyzed highly regio- and stereo-selective hydroborations of internal alkynes with diborane in water

Xuan, Qing-Qing,Wei, Ya-Hui,Song, Qiu-Ling

, p. 1163 - 1166 (2017/06/19)

The highly regio- and stereoselective hydroborations of unactivated internal alkynes with diboron compound catalyzed by Cu(OTf)2 with spiro(phosphoamidite) as ligand in the presence of Cs2CO3 in water was developed. This p

CuCl-K2CO3-catalyzed highly selective borylcupration of internal alkynes - Ligand effect

Yuan, Weiming,Ma, Shengming

supporting information; experimental part, p. 7266 - 7268 (2012/10/07)

An efficient and practical copper-catalyzed highly regio- and stereoselective borylcupration of internal alkynes with bis(pinacolato)diboron using a catalytic amount of K2CO3 as base producing Z-alkenylboron compounds has been demonstrated by applying the ligand effect: commercially available electron-rich tris(p-methoxyphenyl) phosphine ensures a smooth and efficient reaction. Functionalized alkynes, such as propargylic alcohols and derivatives as well as N-propargyl tosylamide, may also be used with excellent selectivity.

Highly regio- and stereoselective synthesis of alkenylboronic esters by copper-catalyzed boron additions to disubstituted alkynes

Kim, Hye Ryung,Yun, Jaesook

supporting information; experimental part, p. 2943 - 2945 (2011/05/04)

The copper-catalyzed addition of bis(pinacolato)diboron to internal alkynes in the presence of methanol generates alkenylboron compounds with high levels of regio- and stereoselectivities. The catalytic efficiency is increased by using monodentate phosphine ligands, especially P(p-tolyl)3 and a range of internal alkynes was borylated in good yields. The Royal Society of Chemistry.
