51379-76-1 Usage
Preparation
Preparation by reaction of propionyl chloride with 1,2,3,5-tetramethoxybenzene (m.p. 47°) in the presence of aluminum chloride in ethyl ether first at 0°, then at r.t., (56%) or in carbon disulfide at r.t. for 3-4h (33%).
Check Digit Verification of cas no
The CAS Registry Mumber 51379-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,7 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51379-76:
(7*5)+(6*1)+(5*3)+(4*7)+(3*9)+(2*7)+(1*6)=131
131 % 10 = 1
So 51379-76-1 is a valid CAS Registry Number.

5,6,7- and 5,7,8-Trioxygenated 3',4'-dihydroxyflavones were derivatized by introducing alkyl groups of various chain lengths at the 3-position of the flavone skeleton.These compounds were tested as inhibitors for arachidonate 5-lipoxygenase purified from
