1,4-Naphthalenedione, 5-methoxy-7-methyl-, also known as 5-methoxy-7-methyl-1,4-naphthoquinone, is an organic compound with the chemical formula C12H10O3. It is a derivative of naphthalene, a bicyclic aromatic hydrocarbon, and features a quinone functional group, which consists of two carbonyl groups (C=O) attached to adjacent carbon atoms. The molecule has a methyl group (-CH3) at the 7-position and a methoxy group (-OCH3) at the 5-position, which are substituents that modify the chemical properties and reactivity of the parent naphthalene structure. 1,4-Naphthalenedione, 5-methoxy-7-methyl- is of interest in various fields, including organic chemistry and pharmaceutical research, due to its potential applications and unique chemical properties.
The CAS Registry Mumber 65565-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,6 and 5 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 65565-56: (7*6)+(6*5)+(5*5)+(4*6)+(3*5)+(2*5)+(1*6)=152 152 % 10 = 2 So 65565-56-2 is a valid CAS Registry Number.
