142286-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142286-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,8 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142286-44:
(8*1)+(7*4)+(6*2)+(5*2)+(4*8)+(3*6)+(2*4)+(1*4)=120
120 % 10 = 0
So 142286-44-0 is a valid CAS Registry Number.

Stereoselective synthesis of 2,3-epoxy sulphoxides
Rayner,Sin,Westwell
, p. 7237 - 7240 (2007/10/02)
Methods for the diastereoselective preparation of various 2,3-epoxy sulphoxides are described using a double enantioselective oxidation approach. Direct comparisons of the selectivity and efficiency of the Davis and Kagan asymmetric sulphur oxidation procedures are given.
