126541-65-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126541-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,4 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126541-65:
(8*1)+(7*2)+(6*6)+(5*5)+(4*4)+(3*1)+(2*6)+(1*5)=119
119 % 10 = 9
So 126541-65-9 is a valid CAS Registry Number.

aminoalkylbenzotriazoles: Reagents for the aminoalkylation of electron rich heterocycles

Katritzky,Yang,Lam

, p. 4971 - 4978 (1992)

Secondary and tertiary aminoalkylbenzotriazoles react with pyrrole, indole, their N-methyl analogs and with 2-methylfuran under mild reaction conditions in the presence of a Lewis acid to afford selectively the corresponding secondary or tertiary amines.

The N-Substitution of Aliphatic Primary Amines via 1-benzotriazoles: Preparation of Secondary Amines

Katritzky, Alan R.,Glen, Noble,Pilarski, Boguslaw,Harris, Philip

, p. 1443 - 1446 (2007/10/02)

A new method has been developed for the selective conversion of primary aliphatic amines into unsymmetrical secondary amines by Grignard reaction of 1-benzotriazoles 1.This method employs simple procedures and mild conditions, and is specific in that onyl monoalkylation of the primary amines results.
