Calculate Digit Verification of CAS Registry Number 624732-06:
(8*6)+(7*2)+(6*4)+(5*7)+(4*3)+(3*2)+(2*0)+(1*6)=145
145 % 10 = 5
So 624732-06-5 is a valid CAS Registry Number.

Highly Diastereoselective Simmons-Smith Cyclopropanation of Allylic Amines

Aggarwal, Varinder K.,Fang, Guang Yu,Meek, Graham

, p. 4417 - 4420 (2007/10/03)

(Equation presented) Cyclopropanation of allylic tertiary amines using the Simmons-Smith reagent has been achieved by employing chelating groups in close proximity to the amine. The chelating groups promote cyclopropanation at the expense of N-ylide formation. Using pseudoephedrine as the chelating group, high diastereoselectivity is observed.
