81023-44-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81023-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81023-44:
(7*8)+(6*1)+(5*0)+(4*2)+(3*3)+(2*4)+(1*4)=91
91 % 10 = 1
So 81023-44-1 is a valid CAS Registry Number.

Syntheses and Properties of Highly Substituted Vinamidines
Knorr, Rudolf,Weiss, Alfons
, p. 139 - 160 (2007/10/02)
Reactions of 1-azaallyl anions 5 with imidic acid derivatives to produce highly substituted vinamidines (8 - 10) or their tautomers 6 are described, and their scope is investigated.This α-iminoalkylation reaction corresponds in its regioselectivity to the
