Check Digit Verification of cas no

The CAS Registry Mumber 872104-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,1,0 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 872104-47:
(8*8)+(7*7)+(6*2)+(5*1)+(4*0)+(3*4)+(2*4)+(1*7)=157
157 % 10 = 7
So 872104-47-7 is a valid CAS Registry Number.

Synthesis, structure and spectroscopic properties of novel 9,10-bis{[6-(diphenylphosphanyl)-2-pyridylmethyl]propylaminomethyl} anthracene-bridged group 11 metal (M = CuI and AgI) dinuclear complexes

Xu, Hu,Xu, Feng-Bo,Li, Qing-Shan,Duo, Wei-Guo,Song, Hai-Bin,Zhang, Zheng-Zhi

, p. 2869 - 2874 (2005)

Dinuclear complexes [M2(μ-BPNNAn)]X2 (M = Cu I, X = ClO4- 1, 1X = BF4- 2; M = AgI, X = BF4- 3, X = ClO 4- 4) have been prepared by treating 9,10-bis{[6- (diphenylphosphanyl)-2-pyridylmethyl]propylaminomethyl}anthracene (BPNNAn) with M(CH3CN)4X in CH2Cl2. The structures of complexes 1, 2 and 3 have been determined by single-crystal X-ray diffraction studies. In the complexes, BPNNAn acts as a chelating ligand and two metal ions riding on two bridgehead carbon atoms in the anthracene group leads to the deformation of the anthracenyl ring. The Cu-Arene charge transfer interaction is observed from the nonfluorescent emission of Cu complex 1, while the Ag complex 3 exhibits dual emission at high concentrations in a CH 2Cl2 solution.
