Calculate Digit Verification of CAS Registry Number 866050-58:
(8*8)+(7*6)+(6*6)+(5*0)+(4*5)+(3*0)+(2*5)+(1*8)=180
180 % 10 = 0
So 866050-58-0 is a valid CAS Registry Number.

Synthesis and tranquillizing effect of new 1,4-benzoxazepines

Botros,Naguib,Osman

, p. 565 - 578 (2013/05/08)

A SERIES of new 1,4-benzoxazepin-5(4H)-ones was prepared by alkylation of salicylamides with phenacyl bromides followed by cyclodehydration of the resulting amides. Treatment of the 1,4-benzoxazepine-5(4H)-ones with phosphorus pentasulphide afforded the corresponding 1,4-benzoxazepine-5(4H)-thiones. N-alkylation of the 1,4-benzoxazepin-5(4H)-ones and S-alkylation of the 1,4-benzoxazepine-5(4H)-thiones were described. Some of the new compounds were subjected to preliminary screening for their tranquilizing effect.
