Abstract
The purpose of the note is to show the usefulness of a simple criterion of density of a subalgebra $\mathcal A\subset L(X)$ in the strong operator topology for arbitrary real or complex locally convex vector space $X$. After proving the criterion we observe its efficiency obtaining short proofs of three important known density theorems plus a new one.
