2-Methyl-4-fluoro-naphthalene is an organic compound with the molecular formula C11H9F. It is a derivative of naphthalene, a polycyclic aromatic hydrocarbon, characterized by the presence of a methyl group at the 2nd carbon position and a fluorine atom at the 4th carbon position. This chemical is a colorless to pale yellow liquid with a strong aromatic odor. It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its potential applications and the presence of fluorine, which can significantly alter the physical and chemical properties of molecules, 2-methyl-4-fluoro-naphthalene is of interest in the field of fluorochemistry.
The CAS Registry Mumber 319-15-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 9 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 319-15: (5*3)+(4*1)+(3*9)+(2*1)+(1*5)=53 53 % 10 = 3 So 319-15-3 is a valid CAS Registry Number.
