The following automatic conversions were performed:

'_chemical_melting_point' value '493 K' was changed to '493' - the
value should be numeric and without a unit
designator.

'_atom_sites_solution_primary' value 'Other' changed to
'other' according to
/usr/data/users/saulius/crontab/automatic-downloads/rss-feeds/RSC/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.
