Taking smiles from pubchem

I noticed that the rdkit canonical smiles node does not always recognize the smiles in my original data set. After I use this node, there is always a certain number of rows with a ? in the canonical smiles column. Rather than manually going into pubchem with the molecule’s SID or REGID number to paste the canonical smile in my data, I wanted to know if there was a node that would automatically do this, given the molecules SID and REGID?
