Task: Please generate a SMILES based on the description below.
Description: The molecule is a mannarate(2-) that is the dianion obtained by the deprotonation of the carboxy groups of D-mannaric acid. It is a conjugate base of a D-mannarate(1-). It is an enantiomer of a L-mannarate(2-).
Result: O=C([O-])[C@@H](O)[C@@H](O)[C@H](O)[C@H](O)C(=O)[O-]
