Uses
5β-Cholanic Acid-3α, 6β-Diol is a cholesterol derivative; Plasma lipophilic biomarkers in rats. Also, it is one of two major metabolites from the hydroxylation of hepatic lithocholic acid catalyzed by Cyp3a/Cyp3a11 enzymes in mice.
Check Digit Verification of cas no
The CAS Registry Mumber 668-49-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 668-49:
(5*6)+(4*6)+(3*8)+(2*4)+(1*9)=95
95 % 10 = 5
So 668-49-5 is a valid CAS Registry Number.

Catalytic oxidations of steroid substrates by artificial cytochrome p-450 enzymes.
Yang, Jerry,Gabriele, Bartolo,Belvedere, Sandro,Huang, Ying,Breslow, Ronald

Catalysts comprising manganese-porphyrins carrying cyclodextrin binding groups are able to perform hydroxylations with substrate selectivity and regio- and stereoselectivity and high catalytic turnovers. The geometries of the catalyst/substrate complexes override intrinsic substrate reactivities, permitting attack on geometrically accessible saturated carbons of steroids in the presence of secondary carbinol groups and carbon-carbon double bonds, as in enzymatic reactions. Selective hydroxylations of steroid carbon 9 positions are of particular practical interest.
