  2. $R$ is Noetherian and $\dim (R) = 0$,

  3. $R$ has finite length as a module over itself,

  4. $R$ is a finite product of Artinian local rings,

  5. $R$ is Noetherian and $\mathop{\mathrm{Spec}}(R)$ is a finite discrete topological space,

  6. $R$ is a finite product of Noetherian local rings of dimension $0$,

  7. $R$ is a finite product of Noetherian local rings $R_ i$ with $d(R_ i) = 0$,

  8. $R$ is a finite product of Noetherian local rings $R_ i$ whose maximal ideals are nilpotent,
