User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a naphthalenesulfonic acid that is the free acid form of the dye Sirius red F3B. The hexasodium salt is a histological dye used principally in staining methods for collagen and amyloid. It has a role as a fluorochrome and a histological dye. It is a member of ureas, a member of naphthols, a naphthalenesulfonic acid and a member of azobenzenes. It is a conjugate acid of a Sirius red F3B(6-).
Assistant: This is a molecule that fits your description: O=C(Nc1ccc2c(O)c(N=Nc3ccc(N=Nc4ccc(S(=O)(=O)O)cc4)cc3S(=O)(=O)O)c(S(=O)(=O)O)cc2c1)Nc1ccc2c(O)c(N=Nc3ccc(N=Nc4ccc(S(=O)(=O)O)cc4)cc3S(=O)(=O)O)c(S(=O)(=O)O)cc2c1
