Check Digit Verification of cas no

The CAS Registry Mumber 50394-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50394-90:
(7*5)+(6*0)+(5*3)+(4*9)+(3*4)+(2*9)+(1*0)=116
116 % 10 = 6
So 50394-90-6 is a valid CAS Registry Number.

Microbial transformation of antifertility agents, norethisterone and 17α-ethynylestradiol

Choudhary, Muhammad I.,Musharraf, Syed G.,Ali, Rahat A.,Atif, Muhammad,Atta-ur-Rahman

, p. 319 - 323 (2007/10/03)

The microbial transformation of oral contraceptive norethisterone (1) by Cephalosporium aphidicola afforded an oxidized metabolite, 17α- ethynylestradiol (2), while the microbial transformation of 2 by Cunninghamella elegans yielded several metabolites, 19-nor-17α-pregna-1,3,5 (1O)-trien-20-yne-3,4,17β-triol (3), 19-nor-17β-pregna-1,3,5 (10)-trien-20-yne-3,7α,17β-triol (4), 19-nor-17α-pregna-1,3,5 (10)-trien-20-yne-3,11α,17β-triol(5), 19-nor-17α-pregna-1,3,5 (10)-trien-20-yne-3,6β,17β-triol (6) and 19-nor-17α-pregna-1,3,5 (10)-trien-20-yne-3,17β-diol-6β-methoxy (7). Metabolite 7 was found to be a new compound. These metabolites were structurally characterized on the basis of spectroscopic techniques.

Synthesis of 2 hydroxy ethynylestradiol and 4 hydroxy ethynylestradiol

Gelbke,Ball,Haupt,Knuppen

, p. 151 - 152 (2007/10/14)

The preparation of 2 hydroxy ethynylestradiol and 4 hydroxy ethynylestradiol is described by oxidation of ethynylestradiol with potassium nitrosodisulfonate and subsequent reduction with KI. These new catechol estrogens are characterized by their spectros
