Check Digit Verification of cas no
The CAS Registry Mumber 169613-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,1 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 169613-97:
(8*1)+(7*6)+(6*9)+(5*6)+(4*1)+(3*3)+(2*9)+(1*7)=172
172 % 10 = 2
So 169613-97-2 is a valid CAS Registry Number.

Chemoenzymatic route to S-betaxolol
Li, Yong-Hong,Huang, Li-Hua,Liu, Hong-Min
, p. 2468 - 2474 (2011)
An efficient chemoenzymatic route to S-betaxolol is reported. A strain (Rhodotorula mucilaginosa DQ832198) screened from soil was used as biocatalyst for the kinetic resolution of the key acetylated intermediates. Excellent enantiomeric excess (ee99%) was
