Can it read a misspelled name?

Only if PubChem recognizes it. Check the spelling, or paste a SMILES.

Where do the other names come from?

From Athanor’s names index (ChEBI and Wikidata), or from PubChem when the index has none; the source is named under the list.

Does it keep stereochemistry?

Yes. A name that states stereochemistry, such as L-alanine, is drawn with its stereocenter.

Is what I type saved?

No. It is sent to PubChem to look it up, and nothing is kept.

How to do it

Type a name, a CAS number or a SMILES.
Athanor draws the structure and lists its formula, mass and other names.
Copy the SMILES or open the structure in the full editor.

Which names it understands

Common names (caffeine), systematic IUPAC names (2-methylbutan-2-ol), CAS numbers (69-72-7) and SMILES. Names and CAS numbers are looked up in PubChem, the U.S. National Library of Medicine’s open chemistry database, and a SMILES is drawn directly. The other names come from Athanor’s names index, built from ChEBI and Wikidata, and the index form of a name is labeled as such.

In the Athanor app, Athanor names any structure you draw with its own rules and checks the name against OPSIN in one click.
