4,4'-dioxo-4,4'-(4,4'-methanediyl-di-phenyl)-di-trans-crotonic acid is a complex organic compound with the molecular formula C20H18O6. It is characterized by a diphenylmethane core, which connects two trans-crotonic acid units through their double bonds. The term "4,4'-dioxo" indicates the presence of two carbonyl groups (C=O) at the 4,4' positions, while "trans" refers to the geometric isomerism of the double bonds, which are on opposite sides of the molecule. 4,4'-dioxo-4,4'-(4,4'-methanediyl-di-phenyl)-di-trans-crotonic acid is known for its potential applications in the synthesis of various pharmaceuticals and materials due to its unique structure and reactivity. It is important to note that handling and use of such chemicals require appropriate safety measures and expertise, given their potential reactivity and the need for controlled synthesis conditions.
The CAS Registry Mumber 4568-53-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,6 and 8 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4568-53: (6*4)+(5*5)+(4*6)+(3*8)+(2*5)+(1*3)=110 110 % 10 = 0 So 4568-53-0 is a valid CAS Registry Number.
