Check Digit Verification of cas no

The CAS Registry Mumber 78365-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,6 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78365-59:
(7*7)+(6*8)+(5*3)+(4*6)+(3*5)+(2*5)+(1*9)=170
170 % 10 = 0
So 78365-59-0 is a valid CAS Registry Number.

Rearrangement/fragmentation reactions of oligosilanes with aluminum chloride

Wagner, Harald,Baumgartner, Judith,Marschner, Christoph,Poelt, Peter

experimental part, p. 3939 - 3954 (2011/10/03)

Reinvestigation of the Lewis acid catalyzed rearrangement of some open-chain permethyloligosilanes with the Al(Fe)Cl3 catalyst system exhibited several cases of additional reactivity: namely, a fragmentation/ cyclization reaction. Introduction of (trimethylsilyl)methyl substituents into the oligosilane substrates strongly facilitated this reaction, yielding cyclic or bicyclic carbacyclosilanes. Investigations concerning the composition of the catalyst system indicated that the incorporation of about 0.1% FeCl3 into the AlCl3 lattice provided an effective catalyst.
