If the CIF is syntactically sound, some additional checks are then carried out on the structure it reports. These are a subset of the numeric checks carried out in Chester when a paper is submitted; this set will be expanded as more types of checking are fully automated. At present, you will be told if your paper is lacking any of the requirements stipulated by the Commission on Journals; some physical quantities will be calculated and compared with values in your file; and the MISSYM algorithm will check for the possible presence of higher space-group symmetry.
The results of all these checks will be mailed to you in a single summary report.
