Check Digit Verification of cas no

The CAS Registry Mumber 613669-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,6,6 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 613669-92:
(8*6)+(7*1)+(6*3)+(5*6)+(4*6)+(3*9)+(2*9)+(1*2)=174
174 % 10 = 4
So 613669-92-4 is a valid CAS Registry Number.

Use of lipase-catalyzed kinetic resolution for the enantioselective approach toward sesquiterpenes containing quaternary centers: The cuparane family

Acherar, Samir,Audran, Gerard,Vanthuyne, Nicolas,Monti, Honore

, p. 2413 - 2418 (2003)

The enzymatic kinetic resolution of a suitable hydroxylated precursor of the deoxygenated molecule 3, a key intermediate in a synthesis of the cuparane skeleton, was investigated by screening a range of lipases for enantioselective transesterification with vinyl acetate. CAL-B proved to be the best lipase, affording both enantiomers in high enantiomeric excess (>98% ee). Single-crystal X-ray diffraction analysis enabled assignment of the absolute configuration and the enantiospecificity of the tested lipases.
