Check Digit Verification of cas no
The CAS Registry Mumber 73642-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,4 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73642-91:
(7*7)+(6*3)+(5*6)+(4*4)+(3*2)+(2*9)+(1*1)=138
138 % 10 = 8
So 73642-91-8 is a valid CAS Registry Number.

Facile one-pot synthesis of α-bromoketones from olefins using bromide/bromate couple as a nonhazardous brominating agent
Patil, Rajendra D.,Joshi, Girdhar,Adimurthy, Subbarayappa,Ranu, Brindaban C.
experimental part, p. 2529 - 2532 (2009/09/06)
A new method for the preparation of α-bromoketones from olefins using bromide/bromate couple as a nonhazardous brominating agent has been developed. Several α-bromoketones were successfully prepared from a variety of olefins by this method. This procedure is an alternative to conventional molecular bromine.
