Task: Please create a SMILES based on the description below.
Description: The molecule is a linear tetrapyrrole anion obtained by deprotonation of the two carboxy groups of mycobilin b; major species at pH 7.3. It is a dicarboxylic acid dianion and a linear tetrapyrrole anion. It is a conjugate base of a mycobilin b.
Result: C=CC1=C(C)C(=O)N=C1/C=c1\[nH]/c(=C\c2[nH]c(C(=O)c3[nH]c(C=O)c(C=C)c3C)c(C)c2CCC(=O)[O-])c(CCC(=O)[O-])c1C
