Check Digit Verification of cas no

The CAS Registry Mumber 140149-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140149-26:
(8*1)+(7*4)+(6*0)+(5*1)+(4*4)+(3*9)+(2*2)+(1*6)=94
94 % 10 = 4
So 140149-26-4 is a valid CAS Registry Number.

SYNTHESE UND REAKTIVITAET VON SILICIUM-UEBERGANGSMETALLKOMPLEXEN. XV. EISEN-SILANE MIT SPERRIGEN ALKYL-LIGANDEN AM SILICIUM

Ries, Wolfgang,Malisch, Wolfgang

, p. 321 - 332 (1983)

The chlorosilanes RSiHCl2 react with Na to give the iron silanes Cp(CO)2FeSiHRCL (Ia-Ic) (R=Et (a), i-Pr (b), t-Bu (c)), which are chlorinated by CCl4 to Cp(CO)2FeSiRCl2 (IIa-IIc).AgBF4 transforms IIb and IIc into the iron fluorosilanes Cp(CO)2FeSiRF2 (IIIb, IIIc).The structure of the new silicon iron complexes is determined by means fo their IR and NMR spectra (1H, 13C, 19F, 29Si).A correlation between the values of ν(SiH) and J(SiH) of Ia-Ic and the Taft constants ? of R is established.
