Check Digit Verification of cas no

The CAS Registry Mumber 142407-31-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,0 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142407-31:
(8*1)+(7*4)+(6*2)+(5*4)+(4*0)+(3*7)+(2*3)+(1*1)=96
96 % 10 = 6
So 142407-31-6 is a valid CAS Registry Number.

Microbiological and chemical methods in the asymmetric oxidation of sulfides: A comparative study for the preparation of (S)-vinyl sulfoxides

Rossi,Fauve,Madesclaire,Roche,Davis,Reddy

, p. 629 - 636 (2007/10/02)

The enantiogenicity of biological and chemical oxidation at the sulfur atom was studied on a series of prochiral vinyl sulfides for the preparation of sulfoxides of (S)-absolute configuration. Using either fungal cultures, Sharpless-modified reagent or chiral oxaziridine, the enantiomeric excesses varied according to the substrate's steric and/or electronic structure; the three methods were complementary.
