1031898-24-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1031898-24-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,8,9 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1031898-24:
(9*1)+(8*0)+(7*3)+(6*1)+(5*8)+(4*9)+(3*8)+(2*2)+(1*4)=144
144 % 10 = 4
So 1031898-24-4 is a valid CAS Registry Number.

Synthesis of multi-substituted 2-iminopyridine by conjugate addition of ethyl cyanoacetate derivatives to alkynyl imines

Hachiya, Iwao,Minami, Yushi,Aramaki, Tetsuya,Shimizu, Makoto

, p. 1411 - 1417 (2008)

The synthesis of multi-substituted 2-iminopyridines by conjugate addition of ethyl cyanoacetate derivatives to alkynyl imines has been developed. The reaction of ethyl cyanoacetate derivatives with alkynyl imines provided multi-substituted 2-iminopyridine

Conjugated imines and iminium salts as versatile acceptors of nucleophiles

Shimizu, Makoto,Hachiya, Iwao,Mizota, Isao

scheme or table, p. 874 - 889 (2009/07/10)

Growing interests in nitrogen-containing molecules involving bioactive and functional materials have stimulated the recent development of synthetic methodologies where nucleophilic addition reactions to imino carbons are utilized in crucial steps. This article summarizes double nucleophilic addition reactions with α,β-unsaturated aldimines, addition reactions using alkynyl imines, "umpoled" reactions of α-imino esters, and the use of iminium salts as reactive electrophiles.
