5-Methoxy-3,4-dihydro-1,7-naphthyridin-2(1H)-one is a heterocyclic organic compound characterized by a 1,7-naphthyridine core, which is a type of fused pyridine ring system. This specific compound features a 3,4-dihydro structure, indicating that there are two hydrogen atoms added across the 3 and 4 positions of the naphthyridine ring, effectively reducing the ring's unsaturation. Additionally, it has a 5-methoxy group attached to the 5-position, which is a methoxy (-OCH3) functional group. The compound is classified as a 2(1H)-one, suggesting the presence of a ketone group at the 2-position, which can form an enol or enolate in solution. This chemical structure is of interest in medicinal chemistry and may have potential applications in the development of pharmaceuticals due to its unique electronic and steric properties.

Check Digit Verification of cas no

The CAS Registry Mumber 82673-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,6,7 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82673-70:
(7*8)+(6*2)+(5*6)+(4*7)+(3*3)+(2*7)+(1*0)=149
149 % 10 = 9
So 82673-70-9 is a valid CAS Registry Number.
