User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is an organic sodium salt resulting from the replacement of the protons from the carboxy groups of fumaric acid by sodium ions. It has a role as a food acidity regulator. It contains a fumarate(2-).
Assistant: This is a molecule that fits this description: O=C([O-])/C=C/C(=O)[O-].[Na+].[Na+]
