RInChI version 1.00

Download the RInChI version 1.00 (23 March 2017) In 2011, the first prototype of RInChI was introduced as version 0.02 based on Python programming (Grethe, Goodman, & Allen, 2013). To make the resulting libraries comparable with InChI deliveries, to increase the search ability of RInChIKeys in the Web by the introduction of the Web-RInChIKey and to fix a number of bugs and development gaps in the former version this new version (version number 1.00) has been created.
