Check Digit Verification of cas no
The CAS Registry Mumber 13470-14-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13470-14:
(7*1)+(6*3)+(5*4)+(4*7)+(3*0)+(2*1)+(1*4)=79
79 % 10 = 9
So 13470-14-9 is a valid CAS Registry Number.

KINETIC STUDIES OF THE SYSTEM TUNGSTEN HEXACHLORIDE/TETRAMETHYLTIN (DIETHYL ETHER)/C5-OLEFINS; DETERMINATION OF THE INITIAL REACTION STEPS.
Thorn-Csanyi,Timm
, p. 37 - 48 (1983)
The initial steps in the catalyst system tungsten hexachloride/tetramethyltin/C//5-olefins have been studied kinetically. UV-vis spectroscopic examinations have shown that the first alkylation step proceeds as a second-order reaction with the low activation energy of 26. 1 kJ mol** minus **1. The reaction between tungsten hexachloride and C//5-olefins leads quantitatively to tungsten pentachloride which is formed as a stable intermediate compound. This reaction, which is much slower than the alkylation step, is of great importance in the presence of high olefin concentrations, and especially in the case of cyclic olefins.
The Use of (Me3Si)2NN(SiMe3)2 as a Reagent for the Synthesis of μ-Dinitrogen Complexes or as a Homogeneous One-electron Reducing Agent
Dilworth, Jonathan R.,Harrison, Stephen J.,Henderson, Richard A.,Walton, David R. M.
, p. 176 - 177 (1984)
The reaction of NbCl5 with (Me3Si)2NN(SiMe3)2, in the presence of tetrahydrofuran (thf) gives high yields (ca. 80percent) of 2N2> (A); (A), or its tantalum analogue, reacts with Me3SiS2CNEt2 to give a high yield of the dinitrogen complexes with exclusively sulphur co-ligands 2N2> (M = Nb or Ta), and reaction of (L = MeCN or thf) with (Me3Si)2NN(SiMe3)2 gives in high yield, together with N2.
