(2,4-dinitro-phenyl)-o-tolyl selenide is an organic compound characterized by the presence of a selenide group (-Se) bonded to an ortho-tolyl group (2-methylphenyl) and a 2,4-dinitrophenyl group. This molecule features a selenium atom that is covalently bonded to the ortho-tolyl and 2,4-dinitrophenyl moieties, creating a unique structure with potential applications in various fields, such as materials science, pharmaceuticals, and chemical research. The compound's properties, including its reactivity, stability, and potential toxicity, are influenced by the presence of the electronegative nitro groups and the heavier chalcogen selenium atom, which can affect its electronic structure and reactivity compared to analogous compounds containing sulfur or oxygen.
The CAS Registry Mumber 1657-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1657-99: (6*1)+(5*6)+(4*5)+(3*7)+(2*9)+(1*9)=104 104 % 10 = 4 So 1657-99-4 is a valid CAS Registry Number.
