81067-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81067-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81067-20:
(7*8)+(6*1)+(5*0)+(4*6)+(3*7)+(2*2)+(1*0)=111
111 % 10 = 1
So 81067-20-1 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
