142066-06-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142066-06-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,6 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142066-06:
(8*1)+(7*4)+(6*2)+(5*0)+(4*6)+(3*6)+(2*0)+(1*6)=96
96 % 10 = 6
So 142066-06-6 is a valid CAS Registry Number.

Brutsche, Andreas,Hartke, Klaus
, 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:
