Check Digit Verification of cas no

The CAS Registry Mumber 145997-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,9,9 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145997-70:
(8*1)+(7*4)+(6*5)+(5*9)+(4*9)+(3*7)+(2*7)+(1*0)=182
182 % 10 = 2
So 145997-70-2 is a valid CAS Registry Number.

The synthesis of chiral 3-oxo-6-[(phenylmethoxy)-carbonyl]-2-piperazineacetic acid esters designed for the presentation of an aspartic acid side chain. A subsequent novel Friedel Crafts reaction

Kogan,Rawson

, p. 7089 - 7092 (2007/10/02)

The syntheses of (2S, 6R)-, and (2S, 6S)-3-oxo-6-[(phenylmethoxy)carbonyl]-2-piperazineacetic acid methyl esters from L- or D-serine and dimethyl-D-malate are described. Acylation of the (2S, 6S) isomer with 3-methoxyphenylacetyl chloride, hydrogenolysis of the benzyl ester, followed by treatment with oxalyl chloride then aluminum chloride led to an unexpected tricyclic product into which a C2O2 unit had been incorporated.
