The CAS Registry Mumber 26040-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,0,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 26040-23:
(7*2)+(6*6)+(5*0)+(4*4)+(3*0)+(2*2)+(1*3)=73
73 % 10 = 3
So 26040-23-3 is a valid CAS Registry Number.

Benzylic Azide Functionalization of Tautomeric o-Acyl-benzoic Acid, -benzamide, and -nicotinic Acid Derivatives, and Thermal Decomposition of the Derived Azides

Takeuchi, Hisato,Eguchi, Shoji

, p. 2149 - 2154 (2007/10/02)

A series of benzylic azido compounds were prepared by the reactions of o-acyl-benzoic acids and -benzamides and pyridine analogues with sodium azide, diphenylphosphoryl azide, and trimethylsilyl azide.Thermal decomposition of the derived benzylic azides afforded three types of rearrangement products.The selectivity of rearrangement depended on the migratory aptitude of substituents and on stereoelectronic factors.
