Check Digit Verification of cas no

The CAS Registry Mumber 141987-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,8 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141987-49:
(8*1)+(7*4)+(6*1)+(5*9)+(4*8)+(3*7)+(2*4)+(1*9)=157
157 % 10 = 7
So 141987-49-7 is a valid CAS Registry Number.

Enzyme Assisted Preparation of Enantiomerically Pure β-Adrenergic Blockers III. Optically Active Chlorohydrin Derivatives and Their Conversion

Ader, Ulrich,Schneider, Manfred P.

, p. 521 - 524 (2007/10/02)

Optical active chlorohydrin derivatives 2a-m and 3a-m of both enantiomeric series were prepared via both enzymatic hydrolyses and acyltransfer reactions catalysed by a highly selective lipase from Pseudomonas sp..The resulting building blocks were further transformed into the corresponding β-blockers of high enantiomeric purity.
