40907-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40907-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40907-20:
(7*4)+(6*0)+(5*9)+(4*0)+(3*7)+(2*2)+(1*0)=98
98 % 10 = 8
So 40907-20-8 is a valid CAS Registry Number.

Base catalysed hydrogenation of methylbromooligosilanes with trialkylstannanes, identification of the first methylbromohydrogenoligosilanes

Herzog,Roewer

, p. 117 - 124 (2007/10/03)

The Lewis base catalysed hydrogenation of methylchlorooligsilanes with trialkylstannanes can also be applied to the hydrogenation of methylbromooligosilanes. In this way methylbromohydrogenoligosilanes were prepared for the first time. Methylbromotrisilanes with an > SiBrMe middle group (e.g. SiBrMe2-SiBrMe-SiBrMe2) are hydrogenated First at this silicon atom under formation of an > SiHMe group (e.g. SiBrMe2-SiHMe-SiBrMe2). Brominated silanes containing a quarternary Si(Si)4 unit (e.g. Si(SiBrMe2)4) do not react with trialkylstannanes.
