Check Digit Verification of cas no
The CAS Registry Mumber 2117-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2117-43:
(6*2)+(5*1)+(4*1)+(3*7)+(2*4)+(1*3)=53
53 % 10 = 3
So 2117-43-3 is a valid CAS Registry Number.

An Efficient Catalyst for the Conversion of Hydrosilanes to Alkoxysilanes
Lorenz, Catrin,Schubert, Ulrich
, p. 1267 - 1270 (2007/10/03)
The copper(I) hydride 6 is an efficient catalyst for the alcoholysis of primary and secondary silanes.The reactions proceed at room temperature within a few hours and give the alkoxysilanes in high yields.Only with bulky alcohols or silanes are longer reaction times and/or increased temperatures required.The presence of air accelarates the reactions and gives rise to higher yields of alkoxysilanes, particularly with bulky alcohols.Diols react with PhRSiH2 (R = Me, Ph) to afford 1,3-dioxo-2-silacycloalkanes and with tertiary silanes to furnish the bissilylated diols.When unsaturated alcohols (2-propen-1-ol or 2-propyn-1-ol) are employed, the double or triple bond is retained. - Keywords: Catalytic silane alcoholysis; Alkoxysilanes
