Check Digit Verification of cas no

The CAS Registry Mumber 68960-59-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,6 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68960-59:
(7*6)+(6*8)+(5*9)+(4*6)+(3*0)+(2*5)+(1*9)=178
178 % 10 = 8
So 68960-59-8 is a valid CAS Registry Number.

Kinetic Resolution by Asymmetric Oxidation of Racemic 3-Azetidinyl P. Tolyl Sulfide with t-Butylhydroperoxide in Presence of a Chiral Titanium Complex

Nemecek, C.,Kagan, H.B.

, p. 2467 - 2476 (2007/10/02)

A chiral reagent based on t-BuOOH and the combination Ti(OiPr)4/(R,R)-DET/H2O=1:2:1 allowed enantioselective oxidation of racemic sulfide β-lactam 2b.By this way recovered 2b could be obtained with ee close to 90percent.The kinetic resolution which was observed was analyzed and discussed. kinetic resolution/β-lactam/racemic sulfide/asymmetric sulfoxidation/hydroperoxide/sulfoxide
