1H-Naphtho[2,1-b]pyran-1-one, 2,3-dihydro-3-(4-methoxyphenyl)- is a complex organic compound with the molecular formula C17H14O3. It is a derivative of naphthopyranone, featuring a naphthalene ring fused to a pyranone ring. The compound is characterized by a 2,3-dihydro structure, indicating the presence of two hydrogen atoms attached to the second and third carbon atoms, which reduces the ring's unsaturation. Additionally, it has a 4-methoxyphenyl group attached to the third carbon, which introduces a methoxy (-OCH3) functional group to the molecule. This chemical structure endows the compound with unique electronic and steric properties, making it a potential candidate for various applications in the fields of chemistry and materials science.

28656-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28656-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,5 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28656-21:
(7*2)+(6*8)+(5*6)+(4*5)+(3*6)+(2*2)+(1*1)=135
135 % 10 = 5
So 28656-21-5 is a valid CAS Registry Number.
