Check Digit Verification of cas no

The CAS Registry Mumber 136781-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136781-40:
(8*1)+(7*3)+(6*6)+(5*7)+(4*8)+(3*1)+(2*4)+(1*0)=143
143 % 10 = 3
So 136781-40-3 is a valid CAS Registry Number.

A FORMAL SYNTHESIS OF ASPARTAME VIA THE OXAZIRIDINE - AMIDE REARRANGEMENT

Duhamel, Pierre,Goument, Bertrand,Plaquevent, Jean - Christophe

, p. 2595 - 2596 (1987)

A formal synthesis of the dipeptide sweetener aspartame via the oxaziridine - amide rearrangement is reported.Thus, the peptidic oxaziridine 4 was prepared and was photochemically isomerized into the aspartame precursor 5.
