Check Digit Verification of cas no

The CAS Registry Mumber 2664-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,6 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2664-25:
(6*2)+(5*6)+(4*6)+(3*4)+(2*2)+(1*5)=87
87 % 10 = 7
So 2664-25-7 is a valid CAS Registry Number.

Electrocatalytic dehalogenation of α-bromoketones in the presence of Cp2TiCl2

Nikitin,Gavrilova,Magdesieva

, p. 1013 - 1019 (2008/09/17)

Processes of direct and electrocatalytic (in the presence of electrochemically reduced Cp2TiCl2) reduction of three α-bromoketones containing the C(sp3)-Br or C(sp2)-Br bond, viz., 2-bromo-and 2,6-dibromo-4,4-dimethylcyclohexa-2,5-dien-1-ones and α-bromo-acetophenone, were studied by cyclic voltammetry and preparative electrolysis. In all cases, the dissociative electron transfer proceeds via the concerted mechanism. Preparative electrolysis of these α-bromoketones in the presence of Cp2TiCl2 affords the reductive debromination products in 40-80% yield at low cathodic potentials (-0.85 V vs. Ag/AgCl/KCl). In the case of 2,6-dibromo-4,4-dimethylcyclohexa-2,5-dien-1-one in the potentiostatic regime, only one bromine atom can be eliminated selectively.
