Check Digit Verification of cas no
The CAS Registry Mumber 24646-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,6,4 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 24646-25:
(7*2)+(6*4)+(5*6)+(4*4)+(3*6)+(2*2)+(1*5)=111
111 % 10 = 1
So 24646-25-1 is a valid CAS Registry Number.

Resolution of 4-Cyano-4-(4-nitrophenyl)hexanoic acid: Synthesis of (R) and (S)-3-(4-aminophenyl)-3-ethylpiperidine- (aminoglutethimide)

Using (R)- or (S)-1-phenylethylamine as a resolving agent, (R)- and (S)-4-cyano-4-(4-nitrophenyl)hexanoic acids have been isolated. Cyclization of each enantiomer, followed by reduction of the nitro group, afforded (R)- and (S)-aminoglutethimide of high (>99% ee enantiomeric purity, respectively. The absolute configuration of (R)-(+)-3-(4-nitrophenyl)-3-ethylpiperidine-2,6-dione was solved by X-ray single crystal analysis thus establishing the (R)-configuration of the dextrorotatory aminoglutethimide. Attempted resolution of the other precursor of aminoglutethimide, 4-cyano-2-ethyl-(4-nitrophenyl)butanoic acid with (S)-1-phenylethylamine led to the formation of the double salt. Its crystal structure was elucidated by X-ray crystallographic analysis.
