Calculate Digit Verification of CAS Registry Number 250643-72:
(8*2)+(7*5)+(6*0)+(5*6)+(4*4)+(3*3)+(2*7)+(1*2)=122
122 % 10 = 2
So 250643-72-2 is a valid CAS Registry Number.

Thermal ring contraction of 3H-1,4-benzo- diazepines into quinazolines

Kaname, Mamoru,Tsuchiya, Takashi,Sashida, Haruki

, p. 2407 - 2413 (2007/10/03)

The thermolysis of the 5-methoxy-(11a-c) and 5-diethylamino-3H-1,4- benzodiazepines (14a-c) resulted in a ring transformation to give the 4- methoxy-(12a-c) and 4-diethylaminoquinazolines (15a-c), respectively. The mechanism of this ring contraction is also described.
