List Version Source flow Name there Why this flow
EF 3.1 658ab93a-edff-463e-8137-6a3239281129 dimethyl malonate The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 1df85166-3c04-5e14-8d2d-0cb8671ffec8 Dimethyl Malonate The CAS numbers are the same (108-59-8); both name the same compartment.

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.
