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 Based on (–)-cytisine alkaloid and ethyl isothiocyanate, N-ethyl-N-cytisinocarbothioamide is synthesized and its structure is proved by 1H NMR spectroscopy and single crystal X-ray diffraction. The mesomeric effect is shown in the carbothioamide group formed. It is found that π-conjugation between nitrogen atoms and the thiocarbonyl group is weakened due to the steric hindrance between hydrogen atoms of the piperidine ring and the thioamide group.
