Check Digit Verification of cas no

The CAS Registry Mumber 91019-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,1 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91019-17:
(7*9)+(6*1)+(5*0)+(4*1)+(3*9)+(2*1)+(1*7)=109
109 % 10 = 9
So 91019-17-9 is a valid CAS Registry Number.

Tertiary Arsine Complexes of Copper and Zinc Group Metals with Coordinated Perchlorate

Naikar, S. B.,Nanje Gowda, N. M.,Reddy, G. K. N.

, p. 133 - 136 (2007/10/02)

A series of three- and four-coordinate perchlorate complexes of copper(I), silver(I), zinc(II) and cadmium(II) of the general compositions: ML2ClO4 (M = Cu, Ag; L = Cy3As; M = Ag; L = Nap2EtAs); M(Cy3As)2(ClO4)2 (M = Zn, Cd), ML3ClO4 (M = Cu, Ag; L = Ph2EtAs, Ph2PrnAs, o-tolyl3P; M = Ag; L = Nap2MeAs); and ML3(ClO4)2 (M = Zn, Cd; L = Ph2MeAs, Ph2EtAs, Ph2PrnAs) have been prepared and characterised by IR and PMR spectroscopy and conductivity measurements.IR spectral data suggest coordination of perchlorate in most of these complexes.The stereochemistry of the complexes depends on the size of the arsine ligands.
