Regulatory Checks by CAS Number: Same Substance, Any Supplier

Apply regulations to every source of the same substance, matched by CAS number.

The problem: the same substance treated as different ingredients

The same substance from different suppliers can slip past a regulatory check if it isn't matched. Missing CAS numbers make the gap worse.

Each supplier's version of a substance gets its own raw material record. If the rule is tied to one record, the others pass unchecked, and if a supplier's data is missing a CAS number, the substance may not be matched at all.

What this demo shows

  1. Match the substance by CAS number across suppliers.
  2. Apply regulations to every source.
  3. Close the gap when a supplier's data is missing a CAS number.

‍

Why it matters

Regulations apply to substances, not to supplier codes. Matching by CAS number means one rule covers the substance from any source, including suppliers added later.

Linking the occasional record without a CAS number closes the gap that would otherwise let a restricted substance through on a technicality.

Read the transcript

Uncountable is where coatings teams build their formulas. A supply problem brings in a second source anti-skinning agent, a new trade name for the same substance. Its CAS number matches the EU rule, so the recipe checks it against the same limit with no new rule to enter. A third supplier's agent has no CAS number on file.

The regulatory team links it to the same rule one time. Now the recipe finds the rule for it too and checks it against the same limit. One substance, any supplier.

FAQs

How are regulations applied to the same substance from different suppliers?

By CAS number. A new supplier's version with a matching CAS number is checked against the same rule automatically.

What if a supplier's material has no CAS number?

The regulatory team links it to the rule once, and the recipe then checks it against the same limit.

Do I need to enter a new rule for each supplier?

No. One rule covers the substance from any supplier.
