Pre-Flight Validation — Bad Data Cannot Reach The Authority

Every substance row is checked while you type. A report cannot be generated with a blocking error outstanding.

  • ▪ Check-digit arithmetic on every CAS and EC / List number — not just the digit pattern. A wrong digit is rejected and the correct one is offered as a one-click fix.
  • ▪ Around 60 ECHA hazard statements, auto-matched from the CLP hazard classes you select, searchable by code or wording.
  • ▪ Advisory flags when your hazard data implies a different Seveso III Annex I category than the one selected, with the suggested category applied in one click.
  • ▪ Blocking errors and advisory warnings listed separately, so you always know what stops the report and what is only a caution.
