Definition: 508373 = 341966 - (52 - 7) - [1 - [(2,4-dichlorophenyl)methyl]-3-[(4-fluorophenyl)methyl]imidazolidine-2,4,5-trione] Defining it: 508373 represents the sum of a negative number and its negation. The negative sign indicates that the original value (52 - 7) is subtracted from 1 to obtain the remaining negative number. The second part evaluates whether there's any residue present in the formula, considering the presence of one molecule of a compound (1). If there's no residue left, this part calculates the difference between two different components of a compound: 3-[(4-fluorophenyl)methyl]-3-[(4-fluorophenyl)methyl]imidazolidine-2,4,5-trione. If the residue is present, it indicates there's some component missing from the original molecule (1). This part adds back that missing component with a positive value of 1.
