Task: Please give me a SMILES based on the text description below.
Description: The molecule is a 2-oxo monocarboxylic acid anion that is the conjugate base of 2-oxopentanoic acid, obtained by deprotonation of the carboxy group. It is a 2-oxo monocarboxylic acid anion and a member of oxopentanoates. It derives from a valerate. It is a conjugate base of a 2-oxopentanoic acid.
Result: CCCC(=O)C(=O)[O-]
