Check Digit Verification of cas no

The CAS Registry Mumber 64528-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,2 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64528-59:
(7*6)+(6*4)+(5*5)+(4*2)+(3*8)+(2*5)+(1*9)=142
142 % 10 = 2
So 64528-59-2 is a valid CAS Registry Number.

Resolution of chiral aliphatic and arylalkyl amines using immobilized Candida antarctica lipase and isolation of their R- and S-enantiomers

Davis,Durden

, p. 569 - 578 (2001)

The resolution of chiral aliphatic and arylalkyl amines in high enantiomeric excess (up to 97.5% ee for the R-enantiomers and up to 99.9% ee for the S-enantiomers) and good yield (50-80%) using immobilized Candida antarctica lipase and ethyl acetate as acyl donor has been demonstrated. A second resolution on the Ramine increased the enantiomeric excess to more than 99.5% (up to 99.9%).
