Check Digit Verification of cas no
The CAS Registry Mumber 604-03-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 604-03:
(5*6)+(4*0)+(3*4)+(2*0)+(1*3)=45
45 % 10 = 5
So 604-03-5 is a valid CAS Registry Number.

HYDROXYLATION OF PROGESTERONE BY CEPHALOSPORIUM APHIDICOLA
Farooq, Afgan,Hanson, James R.,Iqbal, Zahida
, p. 723 - 726 (2007/10/02)
The fungus, Cephalosporium aphidicola, has been shown to hydroxylate progesterone predominantly at the 6β- and 11α-positions.Minor metabolites include tetstosterone acetate, the 20(R)-alcohol and 12β,17α-dihydroxyprogesterone.The sequence involves hydroxylation at 11α and then 6β.The hydroxylations of 11α- and 17α-hydroxyprogesterone and 9β,10α-retroprogesterone have also been examined in the light of these results. - Key words: Cephalosporium aphidicola; progesterone; 9β,10α-retroprogesterone; steroid; microbiological hydroxylation.
