I believe this is the solution:
Here's a text version (made with MathJAX):
$ \begin{array}{|c|c|c|} \hline \begin{array}{|c|c|c|} \hline \color{blue}{ \mathtt{C}} & \mathtt{a} & \mathtt{e} \\ \hline \mathtt{m} & \color{blue}{\mathtt{H}} & \mathtt{i} \\ \hline \color{blue}{\mathtt{S}} & \mathtt{t} & \color{blue}{\mathtt{R}} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \color{blue}{\mathtt{T}} & \mathtt{m} & \mathtt{i} \\ \hline \mathtt{s} & \color{blue}{\mathtt{R}} & \mathtt{a} \\ \hline \mathtt{c} & \mathtt{h} & \color{blue}{\mathtt{E}} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \mathtt{s} & \mathtt{r} & \color{blue}{\mathtt{H}} \\ \hline \mathtt{c} & \mathtt{t} & \color{blue}{\mathtt{E}} \\ \hline \mathtt{i} & \mathtt{m} & \color{blue}{\mathtt{A}} \\ \hline \end{array} \\ \hline \begin{array}{|c|c|c|} \hline \color{blue}{\mathtt{T}} & \mathtt{c} & \mathtt{h} \\ \hline \color{blue}{\mathtt{A}} & \mathtt{i} & \mathtt{m} \\ \hline \color{blue}{\mathtt{R}} & \mathtt{e} & \mathtt{s} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \color{blue}{\mathtt{I}} & \mathtt{a} & \mathtt{m} \\ \hline \mathtt{e} & \color{blue}{\mathtt{S}} & \mathtt{r} \\ \hline \color{blue}{\mathtt{H}} & \mathtt{c} & \color{blue}{\mathtt{T}} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \color{blue}{\mathtt{E}} & \mathtt{s} & \color{blue}{\mathtt{R}} \\ \hline \mathtt{h} & \mathtt{c} & \color{blue}{\mathtt{T}} \\ \hline \mathtt{a} & \mathtt{i} & \mathtt{m} \\ \hline \end{array} \\ \hline \begin{array}{|c|c|c|} \hline \mathtt{i} & \mathtt{s} & \color{blue}{\mathtt{A}} \\ \hline \mathtt{h} & \color{blue}{\mathtt{R}} & \mathtt{c} \\ \hline \color{blue}{\mathtt{E}} & \mathtt{m} & \color{blue}{\mathtt{T}} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \mathtt{r} & \mathtt{t} & \mathtt{h} \\ \hline \color{blue}{\mathtt{M}} & \mathtt{e} & \mathtt{s} \\ \hline \color{blue}{\mathtt{A}} & \mathtt{i} & \mathtt{c} \\ \hline \end{array} & \begin{array}{|c|c|c|} \hline \color{blue}{\mathtt{M}} & \mathtt{e} & \mathtt{c} \\ \hline \mathtt{t} & \color{blue}{\mathtt{A}} & \mathtt{i} \\ \hline \mathtt{r} & \mathtt{h} & \color{blue}{\mathtt{S}} \\ \hline \end{array} \\ \hline \end{array}$
I got this result by systematically going through row by row, column by column, group by group and letter by letter writing down the cell values that had to be a particular letter.
The bold capital letters in the shaded regions are the clues given and everything else is what I typed in.
