2H-1-Benzopyran-2-one, 4-ethyl-7-hydroxy-3-(4-hydroxyphenyl)-, also known as 4-ethyl-7-hydroxy-3-(4-hydroxyphenyl)-2H-1-benzopyran-2-one, is a complex organic compound with the molecular formula C16H14O4. 2H-1-Benzopyran-2-one, 4-ethyl-7-hydroxy-3-(4-hydroxyphenyl)- is characterized by a benzopyran-2-one core structure, which is a type of chromone. It features a 4-ethyl substituent at the 4-position, a hydroxyl group at the 7-position, and a 4-hydroxyphenyl group attached at the 3-position. This specific arrangement of functional groups and substituents gives the molecule unique chemical properties and potential applications in various fields, such as pharmaceuticals or as a precursor in the synthesis of other complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 5217-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5217-90:
(6*5)+(5*2)+(4*1)+(3*7)+(2*9)+(1*0)=83
83 % 10 = 3
So 5217-90-3 is a valid CAS Registry Number.

Synthesis and binding affinity to human α and β estrogen receptors of various 7-hydroxycoumarins substituted at 4- and 3,4- positions

Kirkiacharian, Serge,Lormier, Anh Tuan,Chidiack, Henri,Bouchoux, Franoise,Crde, Evelyne

, p. 981 - 986 (2004)

The study of the relative binding affinity (RBA) to the human α and β estrogen receptors (ERs) of various 7-hydroxycoumarins substituted at 4- and 3,4- positions is weak and lacks in selectivity for both ERα and ERβ. The 4-(4-hydroxyphenyl)-7-hydroxycoumarin shows a weak RBA to ERβ and 3,4-diphenyl-7-hydroxycoumarin presents a stronger RBA to ERα than ERβ.
