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.
New bicyclic aryloxypropynyl alcohols were prepared from stereoisomeric ketones of the phosphabicyclodecane series. Their steric structure was determined from the 1 H and 13 C NMR data. The stereochemistry of ethynylation of the bicyclic ketones was studied in relation to their structure.
