User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an organic sodium salt that is the anhydrous form of the disodium salt of ethylenediaminetetraacetic acid (EDTA). It has a role as a chelator. It contains an EDTA(2-).
Assistant: This is a molecule that fits your description: O=C([O-])C[NH+](CC[NH+](CC(=O)[O-])CC(=O)[O-])CC(=O)[O-].[Na+].[Na+]
