88271-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88271-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 88271-04:
(7*8)+(6*8)+(5*2)+(4*7)+(3*1)+(2*0)+(1*4)=149
149 % 10 = 9
So 88271-04-9 is a valid CAS Registry Number.

A GENERAL SYNTHESIS OF 3-AMINO-2-ALKENENITRILES BY THE CROSS-THORPE REACTION
Kobayashi, Kazuhiro,Hiyama, Tamejiro
, p. 3509 - 3512 (1983)
Highly selective cross-Thorpe reaction is achieved between an α-lithioalkanenitriles and a protected cyanohydrin to give 4-alkoxy-4-amino-2-alkenenitrile, which, in turn, is converted by deprotection and acetylation followed by hydrogenolysis to 3-amino-2
