Check Digit Verification of cas no

The CAS Registry Mumber 7305-47-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7305-47:
(6*7)+(5*3)+(4*0)+(3*5)+(2*4)+(1*7)=87
87 % 10 = 7
So 7305-47-7 is a valid CAS Registry Number.

New Syntheses of 19,21-Dihydropregn-4-ene-3,20-dione, 21-Hydroxy-19-norpregn-4-ene-3,20-dione, and 11β,19,21-trihydroxypregn-4-ene-3,20-dione

Kirk, David N.,Yeoh, Boon Leng

, p. 2945 - 2952 (2007/10/02)

19,21-Dihydroxypregn-4-ene-3,20-dione has been synthesized from 3β-acetoxypregn-5-en-20-one via the "hypoiodite reaction" , and Henbest acetoxylation at C-21; oxidation of the intermediate 21-monoacetate to 19-oxo derivative and alkaline cleavage gave 21-hydroxy-19-norpregn-4-ene-3,20-dione.A similar synthesis of 11β,19,21-trihydroxypregn-4-ene-3,20-dione from 3β-acetoxypregn-5-ene-11,20-dione proceeded through intermediates with the 11β-hydroxy function protected as its acetate.Unusual features mainly of conformational origin were observed in the presence of the 11β-acetoxy substituent; some were helpful to the synthesis, while others led to undesirable side reactions.
