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.
Abstract The coordination reaction of polypyperidol‐4 derivatives with transition metal ions in alcohol‐water solution has been investigated by means of potentiometric and conductometric titration, spectroscopy and viscometry. It was established that the metal ions at first mainly interact with neighbouring pyperidol rings of polymer chain and later the long‐range coordination bonds are formed. The influence of pH values on the stability of complexes is discussed.
