2979-56-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2979-56-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2979-56:
(6*2)+(5*9)+(4*7)+(3*9)+(2*5)+(1*6)=128
128 % 10 = 8
So 2979-56-8 is a valid CAS Registry Number.

, p. 921 - 926 (2007/10/02)
The N-protected α-amino amides 1 are O-alkylated with trialkyloxonium tetrafluoroborates to form the iminium salts 2.Sulfhydrolysis of 2 yields the α-amino thiono esters 3.This reaction sequence allows the preparation of enantiomerically pure 3.Key Words:
