β-Dichloromethylnaphthalene is a chemical compound with the molecular formula C11H8Cl2. It is a derivative of naphthalene, an aromatic hydrocarbon, where two hydrogen atoms are replaced by two chlorine atoms attached to a methyl group. β-dichloromethylnaphthalene is characterized by its potential use as an intermediate in the synthesis of various chemicals, including pharmaceuticals and agrochemicals. It is typically synthesized through the chloromethylation of naphthalene, a process that involves the reaction of naphthalene with formaldehyde and hydrochloric acid. Due to its reactivity and the presence of chlorine atoms, β-dichloromethylnaphthalene can be further functionalized in chemical reactions, making it a valuable building block in organic synthesis. However, like many chlorinated compounds, it may also have environmental and health concerns, and thus its handling and use are subject to safety regulations.

Check Digit Verification of cas no

The CAS Registry Mumber 57803-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,0 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57803-84:
(7*5)+(6*7)+(5*8)+(4*0)+(3*3)+(2*8)+(1*4)=146
146 % 10 = 6
So 57803-84-6 is a valid CAS Registry Number.
