List	Version	Source flow	Name there	Why this flow
EF	3.1	08a91e70-3ddc-11dd-930a-0050c2490048	1,1-Difluoroethane	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
ecoinvent	3.12	94ca9e00-5268-4663-a0cd-25026c7c6b53	1,1-Difluoroethane	The CAS numbers are the same (75-37-6); both name the same compartment.
ecoinvent	3.8	94ca9e00-5268-4663-a0cd-25026c7c6b53	Ethane, 1,1-difluoro-, HFC-152a	The CAS numbers are the same (75-37-6); both name the same compartment.
