2,7-dimethylnaphthalene and 2,4,6-trinitrobenzene-1,3-diol are two distinct chemical compounds with different properties and applications. 2,7-dimethylnaphthalene is a polycyclic aromatic hydrocarbon with a naphthalene core, featuring two methyl groups attached at the 2nd and 7th carbon positions. It is an organic compound that is insoluble in water and has a melting point of 61-62°C. 2,7-dimethylnaphthalene, 2,4,6-trinitrobenzene-1,3-diol is used as a precursor in the synthesis of various chemicals and as a solvent in some industrial processes. On the other hand, 2,4,6-trinitrobenzene-1,3-diol, also known as trinitrophenol or picric acid, is a highly explosive and toxic organic compound. It has a molecular structure consisting of a benzene ring with three nitro groups at the 2nd, 4th, and 6th positions and two hydroxyl groups at the 1st and 3rd positions. Picric acid is a yellow crystalline solid with a melting point of 122°C and is soluble in water. Historically, it has been used as a component of explosives and as a dye, but due to its hazardous nature, its use has been largely discontinued. Both compounds require careful handling and storage due to their potential risks.

Check Digit Verification of cas no

The CAS Registry Mumber 7509-98-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7509-98:
(6*7)+(5*5)+(4*0)+(3*9)+(2*9)+(1*8)=120
120 % 10 = 0
So 7509-98-0 is a valid CAS Registry Number.
