User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a C21-steroid that is 5beta-pregn-11-ene substituted by oxo groups at positions 3 and 20. It is a 20-oxo steroid, a C21-steroid and a 3-oxo-5beta-steroid. It derives from a hydride of a pregnane.
Assistant: This is a molecule that fits your description: CC(=O)[C@H]1CC[C@H]2[C@@H]3CC[C@@H]4CC(=O)CC[C@]4(C)[C@H]3C=C[C@]12C
