Bis(acetyloxy)(biphenyl-4-yl)-λ3-iodane, also known as 4-iodobiphenyl diacetate, is a chemical compound with the molecular formula C16H13IO4. It is a derivative of biphenyl, featuring a central iodine atom bonded to a biphenyl group, with two acetate groups attached to the iodine through oxygen atoms. bis(acetyloxy)(biphenyl-4-yl)-lambda~3~-iodane is often used as a reagent in organic synthesis, particularly in the preparation of various iodinated compounds and as a precursor in the synthesis of pharmaceuticals and other specialty chemicals. Its structure and reactivity make it a valuable tool in the field of chemistry, allowing for the introduction of iodine atoms into organic molecules, which can significantly alter their physical and chemical properties.
The CAS Registry Mumber 5199-03-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 9 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5199-03: (6*5)+(5*1)+(4*9)+(3*9)+(2*0)+(1*3)=101 101 % 10 = 1 So 5199-03-1 is a valid CAS Registry Number.
