Check Digit Verification of cas no

The CAS Registry Mumber 143455-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,5 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143455-13:
(8*1)+(7*4)+(6*3)+(5*4)+(4*5)+(3*5)+(2*1)+(1*3)=114
114 % 10 = 4
So 143455-13-4 is a valid CAS Registry Number.

Synthesis, characterization and biological activity of Cu(II) chelates with some amino acid derivatives

Nandi, M. M.,Choudhury, J.,Tarat, S.

, p. 288 - 291 (2007/10/02)

The complexing behaviour of seventeen amino acid derivatives towards Cu(II) has been studied.Complexes of the types Cu(RH)*xH2O, Cu(RH).Cu(OH)2*xH2O and Cu(R'H)2*yH2O have been prepared and characterized by IR, ESR, electronic spectral, magnetic moment and analytical data.On the basis of differences and direction of the shifts in the IR frequencies of vas OCO and vs OCO modes and ESR spectra, bonding modes of carboxylate group have been established.Biological activitu of complexes is more than that of the free metal ion and the ligands.
