It was developed under the auspices of ([IUPAC](https://iupac.org/)) to represent chemical structures unambiguously and in a machine-readable format. The aim of the system is to facilitate the exchange of chemical information between databases, scientific publications and software applications. + +An InChI describes the structure of a chemical compound using a defined character string, e.g. InChI=1S/CH4/h1H4 for CH4 (methane). Information on the molecular formula, atomic bonding, hydrogen atoms, charges, stereochemistry and isotopic compositions is encoded across several successive levels (‘layers’). This standardised representation enables identical chemical structures to be reliably recognised even when they are stored in different databases or programmes. + +The InChIKey is a shortened form of the InChI. It is a compact hash code consisting of letters, generated from the InChI. The InChIKey is particularly suitable for internet searches and for the rapid indexing of large datasets. + +The key advantages of InChI include its openness, its international standardisation and its high level of interoperability. Unlike proprietary identification systems, the standard can be used freely. + +### CAS-Number {#cas} + +The CAS number (Chemical Abstracts Service Registry Number, ([CAS](https://www.cas.org/) RN®) is a globally recognised identification system for chemical substances. It is assigned by the Chemical Abstracts Service and is used to uniquely identify chemical compounds, polymers, alloys, biomolecules and other substances. The use of CAS numbers allows substances to be uniquely identified, regardless of their name or the language used. + +A CAS number consists of three blocks of numbers separated by hyphens, for example 7732-18-5 for water. The last block of numbers contains a check digit. The number itself does not contain any information about the chemical structure or properties of a substance, but serves solely as a unique identifier. + +The register comprises many millions of substances and is continually being expanded. CAS numbers are used in safety data sheets, scientific publications, patent documents, substance databases and regulatory frameworks. They facilitate the search for chemical substances and help to avoid confusion that may arise from different common names, trade names or systematic names. + +Due to its uniqueness and widespread use, the CAS number is regarded as one of the most important identifiers for chemical substances. However, unlike structure-based identifiers such as InChI, the CAS number does not provide any information about the molecular structure of a compound. + +### ePICs {#epics} The Archival Research Key ([ARK](https://arks.org/about/ark-overview/)) are open identifiers hich are assigned to physical and digital information objects, mostly in the cultural studies. -ARK prefixes are centrally assigned on request by the ARK Alliance and can be resolved centrally on services like [N2T](https://n2t.net/).

Attaching a `?` at the end of an ARK allows adding a structured description of the resource. diff --git a/static/img/topics/InChITrust-padded.jpg b/static/img/topics/InChITrust-padded.jpg new file mode 100644 index 00000000..8edaef47 Binary files /dev/null and b/static/img/topics/InChITrust-padded.jpg differ
