RInChIs, once generated, can provide a compact database for further analysis. The tools for doing this are below, and some helpful information is given in the help pages.

Python 3

Please note that the RInChI code now runs on Python 3

RInChI Addition

RInChIs can be added in such a way that the individual steps for a multistep reaction are combined into a single RInChI describing the whole process.

Enter the RInChIs representing the individual steps below. Be sure to list the steps in the correct order, with each one beginning on a new line.

RInChI Changes

Small lists of RInChI databases can be analysed for the presence and change in rings in greater detail: this script will give the change in rings for each reaction given by size, and, optionally, by composition.
