1136499-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1136499-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,6,4,9 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1136499-07:
(9*1)+(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*9)+(2*0)+(1*7)=164
164 % 10 = 4
So 1136499-07-4 is a valid CAS Registry Number.

IMPROVED PROCESS FOR THE PREPARATION OF (S)-PREGABALIN
-
Page/Page column 8-9, (2009/09/04)
The present invention provides a process for resolving racemic pregabalin to S-pregabalin by using a chiral acid to form a pregabalin salt, purifying the salt to obtain a purified S-pregabalin salt then neutralizing the salt to obtain S-pregabalin having good chiral purity.
