Check Digit Verification of cas no
The CAS Registry Mumber 202120-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,1,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 202120-55:
(8*2)+(7*0)+(6*2)+(5*1)+(4*2)+(3*0)+(2*5)+(1*5)=56
56 % 10 = 6
So 202120-55-6 is a valid CAS Registry Number.

Horse liver esterase catalyzed enantioselective hydrolysis of N,O- diacetyl-2-amino-1-arylethanol
Laib, Taoues,Ouazzani, Jamal,Zhu, Jieping
, p. 169 - 178 (1998)
N,O-Diacetyl-2-amino-1-arylethanol can be efficiently resolved by horse liver esterase (HLE). A remarkable organic co-solvent effect on the enantioselectivity of HLE was observed.
