Check Digit Verification of cas no

The CAS Registry Mumber 40135-93-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,3 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40135-93:
(7*4)+(6*0)+(5*1)+(4*3)+(3*5)+(2*9)+(1*3)=81
81 % 10 = 1
So 40135-93-1 is a valid CAS Registry Number.

Rhodium(I)-catalyzed hydroaminomethylation of 2-isopropenylanilines as a novel route to 1,2,3,4-tetrahydroquinolines

Vieira, Tiago O.,Alper, Howard

, p. 2710 - 2711 (2008/02/08)

A new atom economical approach for the preparation of 1,2,3,4- tetrahydroquinolines can be achieved by means of the intramolecular hydroaminomethylation of 2-isopropenylanilines, mediated by an ionic diamino rhodium catalyst that does not require phosphine - this reaction is highly chemo- and regioselective, and it occurs in good isolated yields.
