Check Digit Verification of cas no

The CAS Registry Mumber 17537-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,3 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17537-13:
(7*1)+(6*7)+(5*5)+(4*3)+(3*7)+(2*1)+(1*3)=112
112 % 10 = 2
So 17537-13-2 is a valid CAS Registry Number.

Iron(II) bromide-catalyzed synthesis of benzimidazoles from aryl azides

Shen, Meihua,Driver, Tom G.

supporting information; experimental part, p. 3367 - 3370 (2009/05/27)

(Chemical Equation Presented) The identity of the ortho-substituent of an aryl azide influences its reactivity toward transition metals. Substitution of a vinyl group with an imine disables rhodium(II)-mediated C-H amination and triggers a Lewis acid mechanism catalyzed by iron(II) bromide to facilitate benzimidazole formation.
