Check Digit Verification of cas no
The CAS Registry Mumber 128241-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,4 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128241-59:
(8*1)+(7*2)+(6*8)+(5*2)+(4*4)+(3*1)+(2*5)+(1*9)=118
118 % 10 = 8
So 128241-59-8 is a valid CAS Registry Number.

Confirmation of the structure of (3S)-3-hydroxyquinine: Synthesis and X-ray crystal structure of its 9-aceto analogue
Srirama Sarma,Han, Dongmei,Deschamps, Jefferey R.,Cook, James M.
, p. 942 - 944 (2005)
3(S)-3-Hydroxyquinine (2) has been separated from its epimeric mixture at C-3 by conversion into the 9-aceto analogue followed by chromatography. The molecular structure of the acetate was determined through single-crystal X-ray analysis, and this confirms the structure of (3S)-3-hydroxyquinine (2), the major metabolite of quinine (1).
