Check Digit Verification of cas no

The CAS Registry Mumber 195197-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,1,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195197-72:
(8*1)+(7*9)+(6*5)+(5*1)+(4*9)+(3*7)+(2*7)+(1*2)=179
179 % 10 = 9
So 195197-72-9 is a valid CAS Registry Number.

Biocatalysis in the chiral recognition of meso-diamides - An efficient route from cyclic olefinic hydrocarbons to optically pure diamino-polyols

Grabowski, Stefan,Armbruster, Joachim,Prinzbach, Horst

, p. 5485 - 5488 (2007/10/03)

meso-Diamino-di(tri,tetr)ols 1-8 were synthesized starting from cheap carbocyclic olefins and cis-diepoxy derivatives. Enantioselective hydrolysis of the corresponding bis(phenylacet)amides with penicillin amidase from E. coli (EC 3.5.1.11) was effected in good yields (73-90%) and with high optical purities (ee 91 - >97).
