Check Digit Verification of cas no

The CAS Registry Mumber 121123-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,2 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121123-17:
(8*1)+(7*2)+(6*1)+(5*1)+(4*2)+(3*3)+(2*1)+(1*7)=59
59 % 10 = 9
So 121123-17-9 is a valid CAS Registry Number.

A NOVEL PROCESS FOR PREPARATION OF CEFPROZIL INTERMEDIATE

-

Page/Page column 7, (2008/06/13)

The present invention relates to a process for preparing a key intermediate of cefprozil and use of this intermediate in the preparation of cefprozil thereby avoiding impurity-causing self-acylation. [R-(Z)]-[4-hydroxy-α-[(3-methoxy-l-methyl-3-oxo-1-propenyl)amino]] benzeneacetic acid, mono potassium salt is reacted with ethyl chloroformate to obtain mixed anhydride which is then silylated with N,O-bis(trimethylsilyl)acetamide. The silylated compound obtained is reacted with [7-trimethylsilylamino-3-(Z/E-propen-1-yl)-3-cephem-4-carboxylic acid]trimethylsilyl ester and deprotected with aqueous hydrochloric acid to give cefprozil.
