Check Digit Verification of cas no

The CAS Registry Mumber 123808-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,0 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123808-17:
(8*1)+(7*2)+(6*3)+(5*8)+(4*0)+(3*8)+(2*1)+(1*7)=113
113 % 10 = 3
So 123808-17-3 is a valid CAS Registry Number.

ENANTIOSELECTIVE SYNTHESIS OF (+)-KJELLMANIANONE

Chen, Bang-Chi,Weismiller, Michael C.,Davis, Franklin A.,Boschelli, Diane,Empfield, James R.,Smith, Amos B.

, p. 173 - 182 (1991)

An asymmetric synthesis of the highly oxygenated cyclopentanoid antibiotic (+)-kjellmanianone (1) has been achieved.The key step entailed enantioselective hydroxylation of the prochiral sodium enolate of β-keto ester 2 with the new, enatiomerically pure N-sulfonyloxaziridine 7b, affording 1 in 68.5percent ee (60percent yield).Possible transition state structures for the asymmetric oxidation are evaluated.
