Naphthalene is an organic compound with the formula C10H8, known for its distinct odor and appearance as a white, crystalline solid. It is a polycyclic aromatic hydrocarbon (PAH) consisting of two fused benzene rings and is commonly used in the production of mothballs and as a precursor in the synthesis of various chemicals. On the other hand, 1,3-dinitro-benzene, also known as m-dinitrobenzene, is an organic compound with the formula C6H4N2O4. It is a nitroaromatic compound characterized by the presence of two nitro groups attached to the 1 and 3 positions of a benzene ring. naphthalene; compound with 1,3-dinitro-benzene is used in the production of dyes, explosives, and other chemical intermediates. Both naphthalene and 1,3-dinitro-benzene are important in the chemical industry, but they also have potential health and environmental concerns due to their toxicity and persistence in the environment.
The CAS Registry Mumber 4832-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 2 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4832-38: (6*4)+(5*8)+(4*3)+(3*2)+(2*3)+(1*8)=96 96 % 10 = 6 So 4832-38-6 is a valid CAS Registry Number.
