949899-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 949899-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,8,9 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 949899-86:
(8*9)+(7*4)+(6*9)+(5*8)+(4*9)+(3*9)+(2*8)+(1*6)=279
279 % 10 = 9
So 949899-86-9 is a valid CAS Registry Number.

PROCESS FOR L-CARNITINE

-

Page/Page column 6, (2008/06/13)

The present invention relates to the process for the preparation of L-carnitine from racemic 3-acyloxy-gamma-butyrolactone or alkyl (R)-4-chloro-3-hydroxybutyrate. In more detail, this present invention relates to the process for the preparation of L-carnitine from (R)-3-hydroxy-gamma-butyrolactone, which was produced from racemic 3-acyloxy-gamma-butyrolactone by stereospecific hydrolysis using enzyme in the aqeous phase or organic phase including aqeous solvent or alkyl (R)-4-chloro-3-hydroxybutyrate, followed by a ring-opening reaction, epoxydation and a nucleophilic substitution by trimethylamine to prepare L-carnitine. The method of making L-carnitine is easier and more economical comparing to the con? ventional methods and L-carnitine produced has higher optical purity.
