Purification Methods
Purify azoxybenzene by chromatography on Al2O3 (*benzene), recrystallise it from hexane or 95% EtOH and dry it by heating under vacuum. The liquid crystals can be sublimed in vacuo.

Check Digit Verification of cas no
The CAS Registry Mumber 2635-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2635-26:
(6*2)+(5*6)+(4*3)+(3*5)+(2*2)+(1*6)=79
79 % 10 = 9
So 2635-26-9 is a valid CAS Registry Number.

The newborn surface of dull metals in organic synthesis. Bismuth-mediated solvent-free one-step conversion of nitroarenes to azoxy- and azoarenes
Wada, Shinobu,Urano, Mika,Suzuki, Hitomi
, p. 8254 - 8257 (2007/10/03)
When milled together with bismuth shots, nitroarenes are readily converted to azoxy- and/or azoarenes depending on substrates and conditions employed. Simple extraction with organic solvent followed by evaporation of the resulting dark pasty solid gave the product in good yield.
