Uses
4,6-Dihydroxy-3(2H)-benzofuranone is an intermediate in synthesizing Diosmetin 3’,7-Diglucuronide-d3 (D485042), a labelled Diosmetin 3’,7-Diglucuronide (D485040), which is a metabolite of Diosmetin (D485000) which is a flavonoid often administered in the treatment of chronic venous insufficiency, hemorrhoids, and related affections.
Check Digit Verification of cas no
The CAS Registry Mumber 3260-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3260-49:
(6*3)+(5*2)+(4*6)+(3*0)+(2*4)+(1*9)=69
69 % 10 = 9
So 3260-49-9 is a valid CAS Registry Number.

Preparation of 4,6,3',4'-tetrasubstituted aurones via aluminium oxide-catalyzed condensation
Bolek, David,Guetschow, Michael
, p. 1399 - 1403 (2007/10/03)
4,6,3',4'-Tetrasubstituted aurones were prepared by a protection- deprotection route with an alumina-catalyzed condensation of 3(2H)-benzofuranones with substituted aldehydes as the key step. Aureusidin (6) was obtained by demethylation of 4,6,3',4'-tetramethoxyaurone (5), a natural product from Cyperus capitatus. 4,6,3',4'-Tetrabenzyloxyaurone (9) was converted in a one hydrogenation-deprotection step to dihydroaureusidin (10).
