Descriptions:
pubchem: Tetracyanoquinodimethane is a quinodimethane that is p-quinodimethane in which the methylidene hydrogens are replaced by cyano groups. It is a nitrile, an alicyclic compound and a quinodimethane. It is functionally related to a p-quinodimethane.
chebi: A quinodimethane that is <em>p</em>-quinodimethane in which the methylidene hydrogens are replaced by cyano groups.
wikipedia: Year 1518 (MDXVIII) was a common year starting on Friday of the Julian calendar. Within much of Christian Europe, New Year's Day was celebrated on January 1, the rule in the Roman Empire since 45 BC, and in 1518, the year ran from January 1, 1518 to December 31, 1518. In England (until 1752) and Scandinavia, the year ran from the Feast of the Annunciation (March 25, 1518) to March 24, 1519; and in France (until 1565) from Easter Sunday (April 4, 1518) to April 23, 1519. For instance, the will of Leonardo da Vinci, drafted in Amboise on 23 April 1519, shows the legend "Given on the 23rd of April 1518, before Easter".* See Wikisource "1911 Encyclopædia Britannica/Easter".
