Check Digit Verification of cas no

The CAS Registry Mumber 1421437-31-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,4,3 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1421437-31:
(9*1)+(8*4)+(7*2)+(6*1)+(5*4)+(4*3)+(3*7)+(2*3)+(1*1)=121
121 % 10 = 1
So 1421437-31-1 is a valid CAS Registry Number.

Rhodium(iii)-catalyzed allylic C-H bond amination. Synthesis of cyclic amines from ω-unsaturated N-sulfonylamines

Cochet, Thomas,Bellosta, Veronique,Roche, Didier,Ortholand, Jean-Yves,Greiner, Alfred,Cossy, Janine

, p. 10745 - 10747 (2012)

For the first time, intramolecular allylic amination was conducted using rhodium(iii) according to an "inner-sphere" type mechanism with amines activated by only one electron-withdrawing group. The activation of C(sp 3)-H bonds was chemoselective and allows the access to a variety of substituted cyclic amines such as pyrrolidines and piperidines.
