Calculate Digit Verification of CAS Registry Number 528812-71:
(8*5)+(7*2)+(6*8)+(5*8)+(4*1)+(3*2)+(2*7)+(1*1)=167
167 % 10 = 7
So 528812-71-7 is a valid CAS Registry Number.

Synthesis and 1,3-dipolar cycloadditions of a new enantiopure cyclic nitrone

Alibés, Ramón,Blanco, Pilar,De March, Pedro,Figueredo, Marta,Font, Josep,álvarez-Larena, ángel,Piniella, Juan F.

, p. 523 - 525 (2007/10/03)

A new enantiopure cyclic nitrone has been efficiently synthesized from a D-glyceraldehyde derivative. Its 1,3-dipolar cycloaddition to different classes of dipolarophiles show complete antifacial selectivity, furnishing highly functionalized enantiopure bicyclic isoxazolidines.
