Check Digit Verification of cas no

The CAS Registry Mumber 107125-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,1,2 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107125-57:
(8*1)+(7*0)+(6*7)+(5*1)+(4*2)+(3*5)+(2*5)+(1*7)=95
95 % 10 = 5
So 107125-57-5 is a valid CAS Registry Number.

REACTION OF HYDROGEN BROMIDE WITH N-ARYL-1,4-BENZOQUINONE MONOIMINES

Burmistrov, K. S.,Toropin, N. V.,Burmistrov, S. I.

, p. 970 - 973 (2007/10/02)

Bromine enters the position ortho to nitrogen on nucleophilic addition of hydrogen bromide to N-phenyl-1,4-benzoquinone monoimine.Bromination of the aryl nucleus is a parallel process, which may be suppressed by adding resorcinol to the reaction mixture.Bromine enters the position ortho to oxygen in the reaction of HBr and N-(2,4-dinitrophenyl)-1,4-benzoquinone monoimine.A dependence of the reactivity on the redox potential of the quinone imine was noted.
