Check Digit Verification of cas no

The CAS Registry Mumber 18557-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,5 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18557-72:
(7*1)+(6*8)+(5*5)+(4*5)+(3*7)+(2*7)+(1*2)=137
137 % 10 = 7
So 18557-72-7 is a valid CAS Registry Number.

The reaction of isosteric isobutyl(isopropoxy)silanes iBun(iPrO)3-nSiH (n = 0-3) with allyl bromide in the presence of platinum compounds

Pikies, J.,Wojnowski, W.

, p. 187 - 193 (2007/10/02)

The isosteric silanes iBun(iPrO)3-nSiH react with allyl bromide to yield the corresponding bromides iBun(iPrO)3-nSiBr.The reactivities of the silanes fall in the sequence: iBu(iPrO)2SiH iBu2(iPrO)SiH > (iPrO)3SiH > iBu3SiH which can be accounted for in terms of the anomeric effects at the silicon atom.

The Mechanism of the Reaction of Molecular Bromine with Organosilicon Hydrides

El-Durini, Nabil M. K.,Jackson, Richard A.

, p. 1275 - 1278 (2007/10/02)

The kinetics of the bromination of 7 triarylsilanes and 14 other organosilicon hydrides by molecular bromine in CCl4 have been determined by the stopped flow method.For triethylsilane, Arrhenius parameters have been measured in octane and CCl4, and solvent effects determined in other solvents of different polarity.The results accord with a molecular mechanism involving one molecule of bromine and one of the organosilicon hydride, with partial positive charge build-up on silicon in the transition state.
