List Version Source flow Name there Why this flow
EF 3.1 349b532c-6a9c-418d-a063-8eadb4d0f3b8 Cyanoacetic acid The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 94f464d4-9e2d-5533-a453-3e121582b592 Cyanoacetic Acid The CAS numbers are the same (372-09-8); both name the same compartment.
ecoinvent 3.12 932d7913-eb64-484c-b2ec-7aae36e29017 Cyanoacetic Acid A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
