Check Digit Verification of cas no
The CAS Registry Mumber 189748-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,4 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 189748-25:
(8*1)+(7*8)+(6*9)+(5*7)+(4*4)+(3*8)+(2*2)+(1*5)=202
202 % 10 = 2
So 189748-25-2 is a valid CAS Registry Number.

Iron(II) bromide-catalyzed intramolecular c-h bond amination [1,2]-shift tandem reactions of aryl azides
Nguyen, Quyen,Nguyen, Tuyen,Driver, Tom G.
, p. 620 - 623 (2013/03/13)
Iron(II) bromide catalyzes the transformation of ortho-substituted aryl azides into 2,3-disubstituted indoles through a tandem ethereal C-H bond amination [1,2]-shift reaction. The preference for the 1,2-shift component of the tandem reaction was established to be Me 1 2 Ph.
