Ammonium sulfate Hepta hydrate
NH4 is ammonium
SO4 is sulfate
Hepta is 7
Hydrate is H2O in this case that has been included in the crystal.
CAS is 7783-20-2

the CAS is of ammonium sulphate. I doubt, that ammonium sulphate forms any hydrate, since the water ioften bound to the cation.

Cis or trans? That's what matters.
