Check Digit Verification of cas no

The CAS Registry Mumber 1421014-36-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,0,1 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1421014-36:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*1)+(3*4)+(2*3)+(1*6)=89
89 % 10 = 9
So 1421014-36-9 is a valid CAS Registry Number.

Synthesis of 15N-labeled vicinal diamines through N-activated chiral aziridines: Tools for the NMR study of platinum-based anticancer compounds

Berger, Gilles,Gelbcke, Michel,Cau?t, Emilie,Luhmer, Michel,Nève, Jean,Dufrasne, Fran?ois

, p. 545 - 548 (2013/02/23)

A new method for the synthesis of 15N-labeled chiral β-diamines from a common precursor, either optically pure amino acids or anti-β-amino alcohols, is reported. The two diastereomeric series of vicinal diamines are produced through the nucleophilic ring opening of activated chiral aziridines. 15N was introduced by means of [ 15N]-benzylamine, prepared from 15NH4Cl. The final compounds are highly valuable because [1H-15N] NMR is considered a powerful tool for studying the chemical properties of platinum-based complexes.
