Check Digit Verification of cas no

The CAS Registry Mumber 151962-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,9,6 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 151962-25:
(8*1)+(7*5)+(6*1)+(5*9)+(4*6)+(3*2)+(2*2)+(1*5)=133
133 % 10 = 3
So 151962-25-3 is a valid CAS Registry Number.

HOMOCHIRAL HETEROORGANIC ANALOGS OF NATURAL COMPOUNDS. III. BIOCATALYTIC METHOD OF OBTAINING HOMOCHIRAL FLUORINE-CONTAINING (R)- AND (S)-PHENYLALANINES AND (S,R)- AND (R,S)-PHENYLSERINES

Soloshonok, V. A.,Shvyadas, V. K.,Kukhar, V. P.,Galaev, I. Yu.,Kozlova, E. V.,Svistunova, N. Yu.

, p. 236 - 240 (2007/10/02)

A convenient biocatalytic method of obtaining homochiral (S)- and (R)-threo-β-(4-fluorophenyl)serine and -2-, -3-, and 4-fluoro- and -2,3,4,5,6-pentafluorophenylalanines by the enantioselective hydrolysis of their racemic N-phenylacetyl derivatives under the action of Escherichia coli penicillin acylase is proposed.
