Check Digit Verification of cas no

The CAS Registry Mumber 245037-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,0,3 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 245037-12:
(8*2)+(7*4)+(6*5)+(5*0)+(4*3)+(3*7)+(2*1)+(1*2)=111
111 % 10 = 1
So 245037-12-1 is a valid CAS Registry Number.

Asymmetric desymmetrization of meso-pyrrolidine derivatives by enantiotopic selective C-H hydroxylation using (salen)manganese(III) complexes

Punniyamurthy,Katsuki, Tsutomu

, p. 9439 - 9454 (2007/10/03)

Chiral (salen)manganese(III) complexes 1 catalyzed the asymmetric desymmetrization of N-protected meso-pyrrolidine derivatives 3, 6-8, 15 and 18 by enantiotopic selective C-H oxidation in the presence of terminal oxidant iodosylbenzene. The oxidation occurred chemoselectively at the carbon α to the nitrogen atom to afford optically active hydroxypyrrolidine derivatives 9, 11, 13, 16, 19 and 21 that were further oxidized to chiral lactams with Jones reagent. The N-protecting groups of the meso-pyrrolidine derivatives have notable effect on the enantioselectivity.
