Update – March 2012

An all-day symposium dedicated to the International Chemical Identifier (InChI) will be held at the 243rd ACS National Meeting in San Diego, CA. In sixteen presentations (including several talks by InChI Trust members and supporters) the current status and future of the InChI will be discussed and the use and usefulness of InChIs in databases, publications, software and other resources will be presented. The InChI Symposium Speakers Dinner is sponsored by the InChI Trust.

The InChI Symposium takes place in Room 27A of the San Diego Convention Center on Wednesday, 28th March 2012, and starts at 8:30 am.


Update – October 2011

The InChI Trust and the International Union of Pure and Applied Chemistry (IUPAC) are pleased to announce the release of a new version of the IUPAC International Chemical Identifier (InChI) software. Version 1.04 of the open source software is now available on the InChI Trust Download page. This version now supports the chemical elements up to 112, copernicium (the last one which is currently recognized by IUPAC; support for elements 105-112 is newly added). The inchi-1 executable (both Windows and Linux versions) now allows the processing of multiple input files in a single run (common file name wildcards are recognized).

The InChI Certification Suite is now available from the InChI Trust. This software was developed to check that an installation of the InChI program has been performed correctly. More information on the InChI Certification Suite and the contact information can be found here.

New InChI working groups on “Inorganics” and “Biopolymers & Proteins” are planned for 2012.


Update – July 2010

The InChI Trust has initiated a contract with GGA Software Services LLC for its subsidiary SciTouch LLC to develop software programs to test and certify that InChIs and InChIKeys produced by whatever means are correct and valid. This work will expand on and make even more robust the original programs developed by NIST as part of the original InChI project. Trust members and others are contributing both large and diverse databases for testing to assure that current and future versions of the InChI software are of the highest possible quality and meet all needs of the community using the InChI algorithms. We expect the testing software to be available in autumn 2010.
