Check Digit Verification of cas no

The CAS Registry Mumber 203715-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,1 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203715-85:
(8*2)+(7*0)+(6*3)+(5*7)+(4*1)+(3*5)+(2*8)+(1*5)=109
109 % 10 = 9
So 203715-85-9 is a valid CAS Registry Number.

Synthesis and characterization of copper (II) complexes with diphenylpyraline hydrochloride

Ramappa,Somasekharappa

, p. 263 - 274 (1998)

A new series of copper complexes formed through the reaction of diphenylpyraline hydrochloride (DP.HCl) with copper(II) salts were synthesized. The solid complexes isolated were characterized by conductivity measurements, elemental analyses and magnetic susceptibility studies. The molecular structure of the Cu(C19H23ON)2Cl2 complex was investigated by X-ray diffraction.
