List Version Source flow Name there Why this flow
EF 3.1 4d9a8790-3ddd-11dd-91de-0050c2490048 lead The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 7b393ae8-add5-5415-9346-d133b32d249a Lead The CAS numbers are the same (7439-92-1); both name the same compartment.
bafu 2026-v1 b260c8cd-aa45-5553-af18-1c891986c193 Lead II The CAS numbers are the same (7439-92-1); both name the same compartment.

Characterisation factors

18

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.
