481-46-9 Usage
Definition
ChEBI: A biflavonoid that is the 7,4'-dimethyl ether derivative of amentoflavone. Isolated from Ginkgo biloba and Dioon, it exhibits anti-HSV-1, antineoplastic and inhibitory activities towards arachidonate 5-lipoxygenase and cyclooxyge
ase 2.
Check Digit Verification of cas no
The CAS Registry Mumber 481-46-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 481-46:
(5*4)+(4*8)+(3*1)+(2*4)+(1*6)=69
69 % 10 = 9
So 481-46-9 is a valid CAS Registry Number.

A new strategy for the synthesis of biflavonoids via arylboronic acids
Muller, Dominique,Fleury, Jean-Pierre
, p. 2229 - 2232 (2007/10/02)
Amentoflavone derivatives were prepared by catalytic coupling of 8-flavone-boronic acids with iodoflavones. 3-Arylflavones, as biflavonoid synthon, are accessible by the method.
