Check Digit Verification of cas no
The CAS Registry Mumber 199396-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,9 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 199396-76:
(8*1)+(7*9)+(6*9)+(5*3)+(4*9)+(3*6)+(2*7)+(1*6)=214
214 % 10 = 4
So 199396-76-4 is a valid CAS Registry Number.

Method for preparing 4-[17beta-methoxy-17alpha-methoxymethyl-3-oxestra-4,9-dien-11beta-yl]benzaldehyde (E)-oxime (asoprisnil)

Page/Page column 7-8, (2009/04/24)
The present invention relates to a method for the reliable and reproducible preparation of 4-[17β-methoxy-17α-methoxymethyl-3-oxoestra-4,9-dien-11β-yl]benzaldehyde (E)-oxime (asoprisnil) on the pilot and manufacturing scale. Asoprisnil, which is prepared by this method, is distinguished by a very good physical stability and is therefore particularly suitable for the manufacture of solid pharmaceutical forms (tablets, coated tablets, etc.).
