Let's break down the expression:

\[
1845 : (-45) + 21 \times (-13)
\]

1. First, perform the division:
   \[
   1845 : (-45) = -41
   \]

2. Next, handle the multiplication:
   \[
   21 \times (-13) = -273
   \]

3. Now, substitute these results into the expression:
   \[
   -41 + (-273) = -41 - 273 = -314
   \]

Thus, the result of the expression is **-314**.
