116315-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116315-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,3,1 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 116315-76:
(8*1)+(7*1)+(6*6)+(5*3)+(4*1)+(3*5)+(2*7)+(1*6)=105
105 % 10 = 5
So 116315-76-5 is a valid CAS Registry Number.

An efficient, highly enantioenriched route to L-carnitine and α-lipoic acid via hydrolytic kinetic resolution

Bose, D. Subhas,Fatima, Liyakat,Rajender, Salla

, p. 1863 - 1867 (2008/01/27)

A general and practical approach for the synthesis of C-4 chiral building blocks using Jacobsen's hydrolytic kinetic resolution technique to resolve terminal epoxides and diols in high enantiomeric excess and excellent yields is described. The utilization of these building blocks for the synthesis of biologically important natural products L-carnitine and α-lipoic acid is illustrated. Georg Thieme Verlag Stuttgart.

SYNTHESES OF α-(R)-AND α-(S)-LIPOIC ACID FROM (S)-MALIC ACID

Brookes, Michael H.,Golding, Bernard T.,Hudson, Alan T.

, p. 9 - 12 (2007/10/02)

(S)-Malic acid has been converted into α-(R)-and α-(S)-lipoic acid via (R)-and (S)-(2-phenylmethoxyethyl)oxirane .The (R)-oxirane (2a) was cleaved with but-3-enylmagnesium bromide (cuprate catalysis) to give (S)-1-(phenylmethoxy)oct-7-en-3-ol (4a).This was converted into methyl (S)-6,8-dihydroxyoctanoate (5a), the di-O-methanesulphonate (6a) of which was treated with sodium sulphide and sulphur in dimethylformamide to yield methyl α-(R)-lipoate (7a), that was saponified to α-(R)-lipoic acid (1a).The (S)-oxirane (2b) was similarly converted into α-(S)-lipoic acid (1b).
