Are OpenEye OEToolkits smiles better supported by rdkit than CACTVS smiles?

[ghost]

Hi,

I encountered some cases where CACTVS smiles were wrongly parsed by rdkit while the OpenEye OEToolkits smiles were correctly parsed by rdkit. The cases were for PDB ligands C3O, ZNE, OCC, C33, TX5, O1C (I obtained the smiles from the following PDB web service: https://data.rcsb.org/rest/v1/core/chemcomp/OCC)

Are OpenEye OEToolkits smiles better supported by rdkit than CACTVS smiles?

Example for ligand OCC:

CACTVS_smiles = 'C[C@H](CCCC(C)(C)O)[C@H]1CC[C@H]2\\C(CCC[C@]12C)=C\\C=C/3C[C@@H](O)[C@H](OCCCO)[C@H](O)C/3=C'
OpenEye_OEToolkits_smiles = 'C[C@H](CCCC(C)(C)O)[C@H]1CC[C@@H]\\2[C@@]1(CCC/C2=C\\C=C/3\\C[C@H]([C@@H]([C@@H](C3=C)O)OCCCO)O)C'

Chem.MolToSmiles(Chem.MolFromSmiles(CACTVS_smiles)) != Chem.MolToSmiles(Chem.MolFromSmiles(OpenEye_OEToolkits_smiles))
True

If I visualise the original smiles in http://www.cheminfo.org/Chemistry/Cheminformatics/Smiles/index.html I can see they are the same:

But after the CACTVS smiles is parsed by rdkit then it becomes a different molecule (the same does not happen with the OpenEye OEToolkits smiles):

Thank you in advance!
