Check Digit Verification of cas no
The CAS Registry Mumber 1312687-84-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,6,8 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1312687-84:
(9*1)+(8*3)+(7*1)+(6*2)+(5*6)+(4*8)+(3*7)+(2*8)+(1*4)=155
155 % 10 = 5
So 1312687-84-5 is a valid CAS Registry Number.

Li, Yong-Hong,Huang, Li-Hua,Liu, Hong-Min
, p. 2468 - 2474 (2011/08/05)
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
