Check Digit Verification of cas no

The CAS Registry Mumber 1239983-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1239983-81:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*8)+(3*3)+(2*8)+(1*1)=203
203 % 10 = 3
So 1239983-81-3 is a valid CAS Registry Number.

Synthesis, chirality and complexation phenomena of two diastereoisomeric dinuclear lanthanide(III) complexes

Murray, Benjamin S.,Parker, David,Dos Santos, Cidalia M. G.,Peacock, Robert D.

experimental part, p. 2663 - 2672 (2010/08/21)

Two diastereoisomeric ditopic ligands have been synthesised by linking (SSS)-hepatadenate triamide derivative of cyclen with a central (SS)- or (SR)- 1, 2-diphenyl-1, 2-diaminoethane derivative. Complexes of selected Ln III ions (Ln = Eu, Tb, Yb) have been characterized and circularly polarised luminescence spectra of the Eu systems revealed significant differences, consistent with a change in overall complex chirality associated with the local helicity at the metal centre. Stepwise binding constants for the formation of 1:1 and 2:1 ternary adducts with (S)-lactate and (S)-O-phospho-tyrosine have been determined, by least-squares analysis of spectral titration data, and emission and 1H NMR spectroscopic data compared with the mononuclear analogue.
