Check Digit Verification of cas no
The CAS Registry Mumber 5062-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,6 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5062-62:
(6*5)+(5*0)+(4*6)+(3*2)+(2*6)+(1*2)=74
74 % 10 = 4
So 5062-62-4 is a valid CAS Registry Number.

Regioselective esterification of polyhydroxylated steroids by Candida antarctica lipase B
Bertinotti, Anna,Carrea, Giacomo,Ottolina, Gianluca,Riva, Sergio
, p. 13165 - 13172 (2007/10/02)
The regioselectivity of Candida antarctica lipase B towards the acetylation of polyhydroxylated steroids has been systematically investigated. The enzyme showed a marked preference for the alcoholic moieties on the A ring and: on the steroidal side chain, making it possible the selective acylation at the positions 3 or 21 of polyhydroxy steroids. Acylation with the synthetically useful esters chloroacetate and levulinate was also accomplished, whereas esterification with benzoate and pivaloate was unsuccessful.
