Check Digit Verification of cas no

The CAS Registry Mumber 1214888-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,4,8,8 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1214888-23:
(9*1)+(8*2)+(7*1)+(6*4)+(5*8)+(4*8)+(3*8)+(2*2)+(1*3)=159
159 % 10 = 9
So 1214888-23-9 is a valid CAS Registry Number.

New modes for the osmium-catalyzed oxidative cyclization

Donohoe, Timothy J.,Lindsay-Scott, Peter J.,Parker, Jeremy S.,Callens, Cedric K. A.

supporting information; experimental part, p. 1060 - 1063 (2010/06/13)

(Figure Presented) The osmium-catalyzed oxidative cyclization of amino alcohol initiators formally derived from 1,4-dienes Is an effective method for the construction of pyrrolidines, utilizing a novel reoxidant (4-nltropyridlne N-oxide = NPNO). The cyclization of enantlopure syn- and anti-amino alcohols gives rise to enantlopure cis- and frans-2,5-disubstituted pyrrolidines, respectively. Moreover, the cyclization of Ws-homoallylic amines bearing an exocyclic chelating group Is shown to be a complementary method for irans-pyrrolidine formation.
