Calculate Digit Verification of CAS Registry Number 1440976-29:
(9*1)+(8*4)+(7*4)+(6*0)+(5*9)+(4*7)+(3*6)+(2*2)+(1*9)=173
173 % 10 = 3
So 1440976-29-3 is a valid CAS Registry Number.

A Csp3-Csp3 bond forming reductive condensation of α-keto esters and enolizable carbon pronucleophiles

Zhao, Wei,Fink, Darla M.,Labutta, Carolyn A.,Radosevich, Alexander T.

supporting information, p. 3090 - 3093 (2013/07/26)

The preparation of densely functionalized unsymmetrical 1,4-dicarbonyl structural motifs by a phosphorus(III)-mediated reductive condensation of α-keto esters and enolizable carbon pronucleophiles is described. The reaction, which is initiated by Kukhtin-Ramirez addition of commercially available tris(dimethylamino)phosphine to the α-keto ester substrate, proceeds rapidly under mild conditions.
