Check Digit Verification of cas no

The CAS Registry Mumber 145028-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,2 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145028-19:
(8*1)+(7*4)+(6*5)+(5*0)+(4*2)+(3*8)+(2*1)+(1*9)=109
109 % 10 = 9
So 145028-19-9 is a valid CAS Registry Number.

Synthesis of C2-symmetric analogues of 4-(pyrrolidino)pyridine: New chiral nucleophilic catalysts

Spivey, Alan C.,Maddaford, Adrian,Fekner, Tomasz,Redgrave, Alison J.,Frampton, Christopher S.

, p. 3460 - 3468 (2007/10/03)

The syntheses of a series of enantiomerically pure C2-symmetric 4-(pyrrolidino)pyridine (PP Y) derivatives by SNAr of 4-halo-/4-phenoxypyridines and by cyclocondensation from 4-aminopyridine are described. Preliminary results pertaining to their use as catalysts for acylative kinetic resolution of 1-phenylethanol are also presented. A single-crystal X-ray analysis of PPY If is reported.
