Check Digit Verification of cas no
The CAS Registry Mumber 51724-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,2 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51724-44:
(7*5)+(6*1)+(5*7)+(4*2)+(3*4)+(2*4)+(1*4)=108
108 % 10 = 8
So 51724-44-8 is a valid CAS Registry Number.

Oxidation of lynestrenol by the fungus Cunninghamella elegans
Iqbal Choudhary,Atif
experimental part, p. 1 - 6 (2010/04/23)
Transformation of lynestrenol (19-nor-17α-pregn-4-en-20-yn-17β- ol) (1) was carried out by incubation with Cunninghamella elegans to obtain 19-nor-17α-pregn-4-en-20-yn-3-one-10β,17β-diol (2), 19-nor-17α-pregn-4-en-20-yn-3-one-6β,17β-diol (3), and 19-nor-17α-pregn-4-en-20-yn-3β,6β,17β-triol (4). Metabolite 4 was identified as a new compound. These metabolites were structurally characterised on the basis of spectroscopic techniques.
