Calculate Digit Verification of CAS Registry Number 119933-90:
(8*1)+(7*1)+(6*9)+(5*9)+(4*3)+(3*3)+(2*9)+(1*0)=153
153 % 10 = 3

Development of a 2-aza-cope-[3 + 2] dipolar cycloaddition strategy for the synthesis of quaternary proline scaffolds

McCormack, Michael P.,Shalumova, Tamila,Tanski, Joseph M.,Waters, Stephen P.

, p. 3906 - 3909 (2010)

A one-pot multicomponent procedure for the synthesis of highly functionalized pyrrolidine rings through a domino 2-aza-Cope-[3 + 2] dipolar cycloaddition sequence has been demonstrated. This protocol was found to be both high-yielding and stereoselective for the endo cycloadduct.
