User: I need a chemical with a acute oral toxicity rat LD50 of 10001.0 mg/kg.
Assistant: Of course Can you provide me with more constraints?
User: The chemical should have a 18 carbon atoms, 0 oxygen atoms, and a molecular mass of 653.730 g/mol. Could you please only provide me with the SMILES and return no other information?
Assistant: ClC1=C(Cl)C2(Cl)C3CCC4C(CCC3C1(Cl)C2(Cl)Cl)C1(Cl)C(Cl)=C(Cl)C4(Cl)C1(Cl)Cl
