Check Digit Verification of cas no

The CAS Registry Mumber 943301-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,3,0 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 943301-90:
(8*9)+(7*4)+(6*3)+(5*3)+(4*0)+(3*1)+(2*9)+(1*0)=154
154 % 10 = 4
So 943301-90-4 is a valid CAS Registry Number.

Highly enantioselective oxidation of sulfides to sulfoxides by a new oxaziridinium salt

Del Rio,Wang,Achab,Bohe

, p. 2265 - 2268 (2008/02/04)

The new oxaziridinium salt 5 (R2 = TBDPS) is an effective reagent for the highly enantioselective oxidation of sulfides to sulfoxides with up to >99% ee and good yields. As such, it represents a new valuable nonmetallic alternative to the existing methods for asymmetric sulfoxidation.
