Check Digit Verification of cas no

The CAS Registry Mumber 142036-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142036-91:
(8*1)+(7*4)+(6*2)+(5*0)+(4*3)+(3*6)+(2*9)+(1*1)=97
97 % 10 = 7
So 142036-91-7 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.
