Check Digit Verification of cas no
The CAS Registry Mumber 939-38-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 939-38:
(5*9)+(4*3)+(3*9)+(2*3)+(1*8)=98
98 % 10 = 8
So 939-38-8 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF OPTICALLY ACTIVE 2-AMINO-1-PHENYLETHANOLS
-
Page/Page column 11-12, (2008/12/06)
Optically active 2-amino-l-phenylethanols of formula (I) or its mirror image, wherein R1 is hydrogen, C1-6alkyl or aryl-substituted C1-6alkyl and R2 through R6 are independently hydrogen, hydroxy or C1-6alkoxy, or salts thereof are prepared by asymmetric hydrogenation of the corresponding 2-aminoacetophenones in the presence of a ruthenium complex catalyst comprising a chiral phosphine ligand.
