The six-digit number at the end of the link is the ZVG number, in this case 010520 for formaldehyde. If the ZVG number has less than six digits, leading zeros have to be added.

A table containing an overview of ZVG number, CAS number, EC number and INDEX number for all GESTIS entries (XLSX, 977 kB) (processed in August 2023) is available for download.

On request, this table can be refined according to individual requirements. This allows to address specific questions. For this purpose, the GESTIS database is searched for certain criteria which can be combined if required. For example:

  • A list of substances that are classified as toxic/hazardous to life and at the same time have an OEL according to TRGS 900.
  • All substances with WGK 3 (German water hazard class 3), but which do not have a GHS classification hazard to aquatic life.
  • A list of all substances for which occupational health data are available in GESTIS.
