1,4-Bis--benzol, also known as 1,4-bis(O-ethyl phosphono vinyl)benzene, is an organophosphorus compound with the chemical formula C12H15O4P2. It is a colorless liquid that is soluble in organic solvents. 1,4-Bis--benzol is characterized by its benzene ring with two vinyl groups attached at the 1 and 4 positions, each featuring an O-ethyl phosphono group. It is used in the synthesis of various organophosphorus compounds and has potential applications in the fields of pharmaceuticals, agrochemicals, and materials science. Due to its phosphorus content, it may also be of interest in the development of flame retardants or as a precursor in the production of specialty chemicals.
The CAS Registry Mumber 5849-51-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 9 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5849-51: (6*5)+(5*8)+(4*4)+(3*9)+(2*5)+(1*1)=124 124 % 10 = 4 So 5849-51-4 is a valid CAS Registry Number.
