Uses

Different sources of media describe the Uses of 41443-60-1 differently. You can refer to the following data:
1. 6,8-Dichloro-octanoic Acid is an Intermediate in the synthesis of α-Lipoic acid (L468750) and its derivatives.
2. 6,8-Dichloro-octanoate is a Intermediate in the synthesis of α-Lipoic acid (L468750) and its derivatives.

Check Digit Verification of cas no

The CAS Registry Mumber 41443-60-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41443-60:
(7*4)+(6*1)+(5*4)+(4*4)+(3*3)+(2*6)+(1*0)=91
91 % 10 = 1
So 41443-60-1 is a valid CAS Registry Number.

Method of preparing R-(+)-alpha-lipoic acid and its salt

-

Page/Page column 3, (2008/06/13)

The present invention discloses a method for preparing R-(+)-LA as well as its metal salts including sodium salt, potassium salt, calcium salt, magnesium salt, zinc salt, ferric salt, cooper salt , lithium salt and its organic salt, wherein a racemic Ethyl 6, 8-Dichlorooctanoic acid is employed as starting agents, followed by a hydrolysis and resolution processes to obtain (+)DCA, and then through sulfuration and cyclization process to obtain R-(+)-LA as well as its varied salts. A method for converting the (?)DCA to (+)DCA is also introduced.
