"4,4'-dioxo-4,4'-bibenzyl-4,4'-diyl-di-trans-crotonic acid" is a complex organic compound with the molecular formula C18H16O6. It is characterized by a central biphenyl core, which is a structure consisting of two benzene rings connected by a single bond. Attached to this core are two crotonic acid groups, which are in the trans configuration, meaning that the double bonds in the crotonic acid groups are on opposite sides of the biphenyl core. The compound is further defined by the presence of two carbonyl groups (indicated by the "4,4'-dioxo" part of the name), which are double-bonded oxygen atoms attached to the carbon atoms of the biphenyl. 4,4'-dioxo-4,4'-bibenzyl-4,4'-diyl-di-trans-crotonic acid is likely to be used in advanced chemical research or as an intermediate in the synthesis of more complex molecules, given its structural complexity.
The CAS Registry Mumber 4479-78-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,7 and 9 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4479-78: (6*4)+(5*4)+(4*7)+(3*9)+(2*7)+(1*8)=121 121 % 10 = 1 So 4479-78-1 is a valid CAS Registry Number.
