Source lists
1| List | Version | Source flow | Name there | Why this flow |
|---|---|---|---|---|
| bafu | 2026-v1 | fcafc4f8-1b3c-5a53-9398-080910db216f | Calcium II | The CAS numbers are the same (14127-61-8); no flow of this substance sat in that compartment, so this one was created for the row. |

Something wrong here?
A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.
- A row from my list should not reach this flow
- This flow is not that chemical
- The compartment or the unit is wrong
You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
