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.
The results of studies on the catalytic hydrogenation of picolinic acid on a cathode activated with skeleton catalysts (Ni, Co) was considered. The main hydrogenation product—2-piperidinecarboxylic acid—is shown to be formed with high ∼95.0–98.0% yields in weakly alkaline catholyte solutions at 40.0°C.
