Bis(3,4,6-trifluor-2,5-dioxo-3,6-cyclohexadien-1-yl)methan, also known as 1,1'-spirobi[isobenzofuran]-3,3',6,6'-tetraone, is a complex organic compound characterized by its unique spirobi[isobenzofuran] structure. It features two isobenzofuran rings connected through a central methane bridge, with each isobenzofuran ring containing three fluorine atoms and two carbonyl groups. This molecule is of interest in the field of organic chemistry, particularly for its potential applications in the synthesis of fluorinated compounds and as a precursor in the preparation of various pharmaceuticals and materials. The compound's stability, reactivity, and electronic properties make it a subject of study for researchers exploring the effects of fluorination on molecular behavior and reactivity.
The CAS Registry Mumber 5736-52-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,3 and 6 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5736-52: (6*5)+(5*7)+(4*3)+(3*6)+(2*5)+(1*2)=107 107 % 10 = 7 So 5736-52-7 is a valid CAS Registry Number.
