The IUPAC International Chemical Identifier (InChI, pronounced "INchee") is a textual identifier for chemical substances designed to provide a standard and human-readable way to encode molecular information and to facilitate the search for such information in databases and on the web. Developed by IUPAC [International Union of Pure and Applied Chemistry] and NIST [National Institute of Standards and Technology] during 2000-2005, the format and algorithms are non-proprietary and the software is freely available under the open source LGPL license (though the term "InChI" is a trademark of IUPAC). 4, record 1, English, - international%20chemical%20identifier

Every InChI starts with the string "InCHI=" followed by the version number, currently 1. The remaining information is structured as a sequence of layers and sub-layers, with each layer providing one specific type of information. The layers and sub-layers are separated by the delimiter "/" and start with a characteristic prefix letter (except for the chemical formula sub-layer of the main layer). 4, record 1, English, - international%20chemical%20identifier

The InChIKey, sometimes referred to as a hashed InChI, is a fixed length (25 character) condensed digital representation of the InChI that is not human-readable. The InChIKey specification was released in September 2007 in order to facilitate web searches for chemical compounds, since these were problematical with the full-length InChI. 4, record 1, English, - international%20chemical%20identifier

Il existe différentes méthodes d’identification internationales : - Le numéro CAS [...]. - Le numéro RTECS [ou les] numéros d’identification de l’ONU utilisés dans le cadre du transport international. [...] Il existe d’autres nomenclatures et systèmes de référencement pour la classification des substances chimiques, y compris les dénominations UICPA [Union internationale de chimie pure et appliquée] attribuées par le «International Chemical Identifier» (InChI) (Service d’Identification International de Produits Chimiques), et les [...] Nombres CE, ces derniers étant attribués par la Commission des Communautés européennes aux substances chimiques disponibles dans le commerce, principalement au sein de l’Union européenne. 4, record 1, French, - identificateur%20chimique%20international

L’IUPAC a lancé une nouvelle version de son système InChI d’identification chimique, InChIKey. Cette version condensée permet de représenter presque n’importe quelle substance chimique avec une série fixe de 25 caractères. Elle pourrait rendre beaucoup plus simple la recherche sur Internet de composés spécifiques en empêchant les coupures imprévisibles et d’autres problèmes rencontrés avec des séries d’InChI de longueur arbitraire. 5, record 1, French, - identificateur%20chimique%20international

identificateur : terme attesté. Le Trésor de la langue française en donne la définition suivante dans le domaine de l’informatique : «Symbole destiné à identifier un corps de données».
