4,5,6,7-Tetramethoxynaphthalene-2-carboxylic acid is a complex organic compound characterized by its unique molecular structure. It features a naphthalene ring, which is a fused pair of benzene rings, with four methoxy groups (-OCH3) attached at positions 4, 5, 6, and 7, and a carboxylic acid group (-COOH) at position 2. 4,5,6,7-tetramethoxynaphthalene-2-carboxylic acid is known for its potential applications in the synthesis of various pharmaceuticals and other organic compounds due to its versatile functional groups. The presence of the carboxylic acid group allows for further chemical reactions, such as esterification or amidation, while the methoxy groups can be involved in demethylation reactions or serve as protecting groups in organic synthesis. The compound's properties, such as solubility and reactivity, can be influenced by the electron-donating nature of the methoxy groups, which can stabilize the molecule and affect its interactions with other chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 2981-93-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,8 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2981-93:
(6*2)+(5*9)+(4*8)+(3*1)+(2*9)+(1*3)=113
113 % 10 = 3
So 2981-93-3 is a valid CAS Registry Number.
