Check Digit Verification of cas no

The CAS Registry Mumber 160707-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,7,0 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160707-39:
(8*1)+(7*6)+(6*0)+(5*7)+(4*0)+(3*7)+(2*3)+(1*9)=121
121 % 10 = 1
So 160707-39-1 is a valid CAS Registry Number.

PROCESSES AND INTERMEDIATES FOR PREPARING 2-SUBSTITUTED PIPERIDINE STEREOISOMERS

-

Page/Page column 5-6, (2008/06/13)

A process for preparing d-threo methyl ±- piperid-2-ylarylacetates of formula III: wherein R 1 is aryl having 6 to 28 carbon atoms, comprising the steps of: reacting a pyridine having formula I: wherein R 1 is aryl having 6 to 28 carbon atoms with hydrogen in an alkanoic acid having 1 to 10 carbon atoms and in the presence of a catalyst to provide a mixture of threo and erythro piperidine stereoisomers having formulas IIa-d: €?€?€? adding an alkyl alkanoate having 2 to 20 carbon atoms to said mixture, thereby precipitating alkanoate salts of said erythro stereoisomers preferentially with respect to alkanoate salts of said threo stereoisomers; reacting said erythro alkanoate salts with aqueous base to form said erythro stereoisomers; reacting said erythro stereoisomers with an acid resolving agent in an alkyl alcohol having 1 to 5 carbon atoms, thereby forming acid salts of said 1-erythro stereoisomers preferentially with respect to said d-erythro stereoisomers; reacting said 1-erythro acid salts with aqueous base to form said 1-erythro piperidine; reacting said 1-erythro piperidine with an alkali metal alkoxide having one to 10 carbon atoms in organic solvent, whereby forming said d-threo piperidine, and converting said d-threo piperidine to said d-threo methyl ±- piperid -2- ylarylacetate.
