(8*1)+(7*2)+(6*5)+(5*8)+(4*2)+(3*8)+(2*1)+(1*3)=129
129 % 10 = 9
So 125828-13-9 is a valid CAS Registry Number.

Synthesis of Acylsilanes from Amides and Esters, and the Selective Oxidation of α-Silyl Alcohols to Aldehydes

Fleming, Ian,Ghosh, Usha

, p. 257 - 262 (2007/10/02)

The acylsilanes 2 can easily be made directly from the dimethylamides 3 by treatment with phenyldimethylsilyllithium.They can also be made in two steps from the esters 4 using 2 equiv. of phenyldimethylsilyllithium followed by oxidation of the disilyl alcohols 5 with PDC.The disilyl alcohols 5 can be used as intermediates in the conversion of esters into aldehydes without recourse to hydride reagents, by monodesilylation, using a Brook rearrangement, followed by oxidation and selective removal of the silyl group, using chromium trioxide in DMSO.
