Check Digit Verification of cas no
The CAS Registry Mumber 72377-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,7 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72377-05:
(7*7)+(6*2)+(5*3)+(4*7)+(3*7)+(2*0)+(1*5)=130
130 % 10 = 0
So 72377-05-0 is a valid CAS Registry Number.

Directed evolution of an enantioselective lipase with broad substrate scope for hydrolysis of α-substituted esters
Engstroem, Karin,Nyhlen, Jonas,Sandstroem, Anders G.,Baeckvall, Jan-E.
supporting information; experimental part, p. 7038 - 7042 (2010/07/05)
A variant of Candida antarctica lipase A (CalA) was developed for the hydrolysis of α-substituted p-nitrophenyl esters by directed evolution. The E values of this variant for 7 different esters was 45-276, which is a large improvement compared to 2-20 for the wild type. The broad substrate scope of this enzyme variant is of synthetic use, and hydrolysis of the tested substrates proceeded with an enantiomeric excess between 95-99%. A 30-fold increase in activity was also observed for most substrates. The developed enzyme variant shows (R)-selectivity, which is reversed compared to the wild type that is (S)-selective for most substrates.
