In Brightway2, you can view the properties of an exchange with exchange.as_dict(). This dictionary contains a lot of information, which are also available on ecoinvent. Unfortunately, I can't find the CAS number as property. Is there a possibility to find the CAS numbers for the reference product of an activity, which are also stored in ecoinvent, in Brightway2?

CAS numbers are available for biosphere flows when they are present:
import bw2data as bd
b = bd.Database("biosphere3")
a = b.random()
a
>>> 'Fludioxonil' (kilogram, None, ('water', 'ground-'))
a['CAS number']
>>> '131341-86-1'
Are there CAS numbers for ecoinvent activities?
