Check Digit Verification of cas no

The CAS Registry Mumber 81601-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,0 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81601-94:
(7*8)+(6*1)+(5*6)+(4*0)+(3*1)+(2*9)+(1*4)=117
117 % 10 = 7
So 81601-94-7 is a valid CAS Registry Number.

Enhancing the enantioselectivity of Candida lipase catalyzed ester hydrolysis via noncovalent enzyme modification

Wu, Shih-Hsiung,Guo, Zhi-Wei,Sih, Charles J.

, p. 1990 - 1995 (1990)

When the lipase of Candida cylindracea was treated with deoxycholate and organic solvents (ether-ethanol, 1:1), the enzyme apparently unfolded and refolded to generate a more stable conformer, termed lipase A-form. This lipase A-form was found to be considerably more enantioselective than the native enzyme toward the hydrolysis of a variety of (±)-arylpropionic and (±)-phenoxypropionic esters.
