Check Digit Verification of cas no

The CAS Registry Mumber 343248-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,2,4 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 343248-67:
(8*3)+(7*4)+(6*3)+(5*2)+(4*4)+(3*8)+(2*6)+(1*7)=139
139 % 10 = 9
So 343248-67-9 is a valid CAS Registry Number.

The synthesis of L-proline derived tetraazamacrocyclic ligands of C2 symmetry via intramolecular ester aminolysis

Achmatowicz, Michal,Jurczak, Janusz

, p. 111 - 119 (2007/10/03)

A convenient and efficient synthesis of enantiomerically pure 12-, 14-, and 16-membered tetraazamacrocyclic ligands, able to form complexes with transition metal cations, is discussed. Linear α,ω-aminoesters, prepared from L-proline, undergo intramolecular aminolysis to afford the corresponding macrocyclic amides in good yields.
