Calculate Digit Verification of CAS Registry Number 94563-08:
(7*9)+(6*4)+(5*5)+(4*6)+(3*3)+(2*0)+(1*8)=153
153 % 10 = 3
So 94563-08-3 is a valid CAS Registry Number.

Thermolysis of Aryl Azides in Phenyl Isocyanate

Patel, Dalpat I.,Smalley, Robert K.

, p. 2587 - 2590 (2007/10/02)

Aryl azides (p-XC6H4N3) decompose in boiling phenyl isocyanate to give mainly 1-phenyl-3-phenylcarbamoyl-2-oxo-1,3-dihydrobenzimidazoles and azo-compounds.In some cases, however (X=Ac, CO2Me, or CN) work-up in methanol solution produces methyl N-arylcarbamates (p-XC6H4NHCO2Me) indicative of the formation of substituted isocyanates (p-XC6H4NCO) during thermolysis.A mechanistic rationale is offered.
