Check Digit Verification of cas no

The CAS Registry Mumber 133520-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133520-33:
(8*1)+(7*3)+(6*3)+(5*5)+(4*2)+(3*0)+(2*3)+(1*3)=89
89 % 10 = 9
So 133520-33-9 is a valid CAS Registry Number.

Asymmetric microbiological Baeyer-Villiger reaction of a bridged bicyclic ketone: Divergent behaviour of its enantiomers

Konigsberger,Alphand,Furstoss,Griengl

, p. 499 - 500 (1991)

The bioconversion of 7-anti-benzyloxymethylbicyclo[2.2.1]hept-5-en-2-one 1 with cells of Acinetobacter calcoaceticus NCIB 9871 has been studied. Its (1R,4S,7R) enantiomer underwent a Baeyer-Villiger oxidation yielding rearranged lactone 2 (ee 85%), whereas (1S,4R,7S)-1 was reduced to alcohols 3-endo (ee 95%) and 3-exo (o.p. 89%).
