Naphthoic acid, also known as naphthalene-2-carboxylic acid, is an organic compound derived from naphthalene, a polycyclic aromatic hydrocarbon. It is a white crystalline solid with a melting point of 180-182°C and is soluble in organic solvents such as ethanol and ether. Naphalic acid has a molecular formula of C11H8O2 and is used in the synthesis of dyes, pharmaceuticals, and other chemical products. It is also employed as a chemical intermediate in the production of various compounds, including naphthol AS, a colorant used in the dyeing and printing of textiles. Due to its potential health and environmental risks, handling and disposal of naphthoic acid must be done with proper safety measures and in compliance with regulations.

Check Digit Verification of cas no

The CAS Registry Mumber 1320-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1320-04:
(6*1)+(5*3)+(4*2)+(3*0)+(2*0)+(1*4)=33
33 % 10 = 3
So 1320-04-3 is a valid CAS Registry Number.
