List Version Source flow Name there Why this flow
EF 3.1 4d9a8790-3ddd-11dd-8db2-0050c2490048 uranium-234 The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 23980c42-4135-5341-b214-15fe6090b1e9 Uranium-234 The CAS numbers are the same (13966-29-5); both name the same compartment.
bafu 2026-v1 eea19c1d-18b2-5cc5-abb9-ba7dd2ec4c9a Uranium-234 The CAS numbers are the same (13966-29-5); both name the same compartment.
