81467-53-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81467-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81467-53:
(7*8)+(6*1)+(5*4)+(4*6)+(3*7)+(2*5)+(1*3)=140
140 % 10 = 0
So 81467-53-0 is a valid CAS Registry Number.

Cyclization of O-Acetoacetylbenzamide Oxime Derivatives

Tabei, Katsumi,Kawashima, Etsuko,Takada, Toyozo,Kato, Tetsuzo

, p. 336 - 340 (2007/10/02)

O-Acetoacetylbenzamide oxime derivatives (2) were prepared from benzamide oxime derivatives (1) and diketene at low temperature in almost quantitative yields.Cyclization of 2 in the presence of a strong base proceeded with elimination of acetone to afford 3-aryl-1,2,4-oxadiazolin-5-one derivatives (4) in 77-95percent yields.However, in the cases of the o-, m-, and p-nitrobenzamide oxime derivatives (2f-h), the reaction proceeded with dehydration even in the presence of a strong base to afford 5-acetonyl-3-aryl-1,2,4-oxadiazole derivatives (3f-h) in moderate yields.Possible mechanisms of these cyclization are discussed.
