127136-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127136-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,3 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127136-98:
(8*1)+(7*2)+(6*7)+(5*1)+(4*3)+(3*6)+(2*9)+(1*8)=125
125 % 10 = 5
So 127136-98-5 is a valid CAS Registry Number.

Guanidine-based task-specific ionic liquids as catalysts for aza-Michael addition under solvent-free conditions

Ying, Anguo,Zheng, Ming,Xu, Haidan,Qiu, Fangli,Ge, Changhua

experimental part, p. 883 - 890 (2012/04/17)

An efficient and facile protocol for aza-Michael addition of aliphatic and aromatic amines to electron-deficit alkenes using [TMG][Lac] as catalyst under solvent-free conditions was established.

ZrOCl2·8H2O on montmorillonite K10 accelerated conjugate addition of amines to α,β-unsaturated alkenes under solvent-free conditions

Hashemi, Mohammed M.,Eftekhari-Sis, Bagher,Abdollahifar, Amir,Khalili, Behzad

, p. 672 - 677 (2007/10/03)

At room temperature, ZrOCl2·8H2O on montmorillonite K10 efficiently catalyzes conjugate addition of amines to a variety of conjugated alkenes such as α,β-unsaturated carbonyl compounds, carboxylic esters, nitriles and amides under solvent-free conditions. The catalyst can be recycled for subsequent reactions without any appreciable loss of efficiency.
