Calculate Digit Verification of CAS Registry Number 221558-23:
(8*2)+(7*2)+(6*1)+(5*5)+(4*5)+(3*8)+(2*2)+(1*3)=112
112 % 10 = 2
So 221558-23-2 is a valid CAS Registry Number.

A novel ring transformation of 5-azidothiazoles

Ceulemans, Erik,Dyall, Leonard K.,Dehaen, Wim

, p. 1977 - 1988 (1999)

The 4-oxoalkyl- and 4-iminoalkyl-5-azidothiazoles undergo a ring transformation with nitrogen loss at relatively low temperatures to afford 4- cyanooxazoles and 4-cyanoimidazoles, respectively. The mechanism, which is thought to involve a ring opening-ring closure process, is discussed.
