Check Digit Verification of cas no

The CAS Registry Mumber 350028-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,0,2 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 350028-10:
(8*3)+(7*5)+(6*0)+(5*0)+(4*2)+(3*8)+(2*1)+(1*0)=93
93 % 10 = 3
So 350028-10-3 is a valid CAS Registry Number.

The synthesis of L-proline derived hexaazamacrocyclic ligands of C3 symmetry via intramolecular methyl ester aminolysis

Achmatowicz, Michal,Jurczak, Janusz

, p. 487 - 495 (2001)

A convenient synthesis of enantiomerically pure 18-, 21-, and 24-membered hexaaza-crown ligands is presented. Linear α,ω-aminoesters, prepared from L-proline, undergo intramolecular aminolysis to afford the corresponding 18-, 21-, and 24-membered macrocyc
