Warfarin metabolite.
Check Digit Verification of cas no
The CAS Registry Mumber 67588-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,8 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67588-18:
(7*6)+(6*7)+(5*5)+(4*8)+(3*8)+(2*1)+(1*8)=175
175 % 10 = 5
So 67588-18-5 is a valid CAS Registry Number.

The first practical asymmetric synthesis of R and S-warfarin
Robinson, Andrea,Li, Hui-Yin,Feaster, John
, p. 8321 - 8324 (2007/10/03)
A highly efficient synthesis of both enantiomers of warfarin Ia and Ib has been developed by using a novel two step 'chiral switch' strategy and a DuPHOS-Rh(I) catalyzed asymmetric hydrogenation.
