Check Digit Verification of cas no
The CAS Registry Mumber 67372-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67372-69:
(7*6)+(6*7)+(5*3)+(4*7)+(3*2)+(2*6)+(1*9)=154
154 % 10 = 4
So 67372-69-4 is a valid CAS Registry Number.

Epoxidation of 17-oxo-15,16-methylene steroids with sulfoxonium ylides
-
Page/Page column 5, (2010/11/30)
A process for the epoxidation of 17-oxo-15,16-methylene steroids, in particular of drospirenone precursors, comprising the use of sulfoxonium ylides, in particular of dimethylsulfoxonium methyl ylide. The process allows to prepare in good yields 17-spiro epoxides, which can be easily transformed into 17-spironolacto-steroids.
