1422193-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422193-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,1,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1422193-40:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*9)+(3*3)+(2*4)+(1*0)=125
125 % 10 = 5
So 1422193-40-5 is a valid CAS Registry Number.

Rh2(II)-catalyzed selective aminomethylene migration from styryl azides
Kong, Chen,Jana, Navendu,Driver, Tom G.
, p. 824 - 827 (2013/03/29)
Rh2(II)-Carboxylate complexes were discovered to promote the selective migration of aminomethylenes in β,β-disubstituted styryl azides to form 2,3-disubstituted indoles. Mechanistic data are also presented that suggest that the migration occurs stepwise before diffusion of the iminium ion.
