4-fluoro-2,6-diiodo-anisole is an organic compound with the chemical formula C7H5FI2O. It is a derivative of anisole, which is a methoxybenzene, and features a fluorine atom at the 4-position, and two iodine atoms at the 2 and 6 positions. 4-fluoro-2,6-diiodo-anisole is characterized by its unique combination of electron-withdrawing fluorine and electron-donating iodine atoms, which can significantly influence its reactivity and physical properties. It is often used in the synthesis of pharmaceuticals and other organic compounds due to its potential to alter the electronic and steric environment of the molecule. The presence of halogen atoms also makes it a candidate for further functional group transformations, such as cross-coupling reactions, which are common in the preparation of complex organic molecules.
The CAS Registry Mumber 343-78-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 3 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 343-78: (5*3)+(4*4)+(3*3)+(2*7)+(1*8)=62 62 % 10 = 2 So 343-78-2 is a valid CAS Registry Number.
