126521-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126521-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,2 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126521-73:
(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*1)+(2*7)+(1*3)=111
111 % 10 = 1
So 126521-73-1 is a valid CAS Registry Number.

Selective halogenation of aromatics by dimethyldioxirane and halogen ions
Bovicelli,Mincione,Antonioletti,Bernini,Colombari
, p. 2955 - 2963 (2007/10/03)
The oxidation of halogen anions by dimethyldioxirane (DMD) produced reactive species which led, in acidic media, to the halogenation of activated aromatic rings. The reaction can be efficiently controlled to obtain selective and mixed halogenated species.
