Check Digit Verification of cas no

The CAS Registry Mumber 87268-28-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87268-28:
(7*8)+(6*7)+(5*2)+(4*6)+(3*8)+(2*2)+(1*8)=168
168 % 10 = 8
So 87268-28-8 is a valid CAS Registry Number.

REARRANGEMENT OF 2,2'-DIPROPIONYLAZOXYBENZENES TO 3-BENZOISOXAZOLES

Mochalov, S. S.,Fedotov, A. N.,Shabarov, Yu. S.

, p. 593 - 598 (2007/10/02)

2,2'-Dipropionylazoxybenzenes undergo rearrangement to the corresponding 3-benzoisoxazoles in the case of base catalysis; this transformation is realized only in the case of ortho,ortho' orientation of the propionyl groups in the substrate molecule and with the participation of the solvent as a reagent.A mechanism for the rearrangement that assumed the participation of one of the propionyl groups in intramolecular reduction of the azoxy group to an azo group is proposed.
