It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Data of the computer simulation of the destructive hydrogenation of coal asphaltene are reported. These data were obtained by quantum-chemical methods for refining the geometric configurations of the asphaltene molecule and its radical fragments (UPM3) and the directions of the unimolecular thermal degradation and hydrogenation of a radical fragment (UHF/6-311 + G(d,p)).
