Check Digit Verification of cas no

The CAS Registry Mumber 97128-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,2 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97128-04:
(7*9)+(6*7)+(5*1)+(4*2)+(3*8)+(2*0)+(1*4)=146
146 % 10 = 6
So 97128-04-6 is a valid CAS Registry Number.

(Phthalocyaninato)iron(II)- and -ruthenium(II) Compounds with Isocyanides as Axial Ligands

Keppeler, Uwe,Kobel, Wolfram,Siehl, Hans-Ullrich,Hanack, Michael

, p. 2095 - 2104 (2007/10/02)

(Phthalocyaninato)iron(II) and -ruthenium(II) (PcM, M = Fe, Ru) react with aliphatic and aromatic monodentate isocyanides RNC (R = t-Bu, c-HX, Bzl, Ph, Me2ph) with formation of the corresponding bisaxial substituted (phthalocyaninato)metal(II) compounds PcM(RNC)2 (M = Fe, Ru) 1-5.The structures of these soluble compounds were determined by 1H and 13C NMR spectroscopy.The influence of the central metal atom M and of the organic group on the ?-donor-?-acceptor properties of the metal-ligand bonds is investigated by IR spectroscopy.UV/VIS spectroscopy , TG/DTG/DTA measurements and FD mass spectroscopy additionally demonstrate the large differences when changing iron against ruthenium in 1-5.The thermal and mass spectroscopic differences point to the existence of pentacoordinated PcRu(II) compounds.
