No, your sentence is not correct.
1. Look at the first two words. If you were trying to use the present tense, you need to add a letter to "donate". If you were trying to use the past tense, you need to add a different letter to the end of "donate".
2. You need to use an article before "charity".
3. It's not a charity "organism". Look up "organism" in the dictionary and you will see that it is not appropriate.
Look at the corrections I have made in red. Don't put a space before a full stop, a question mark or an exclamation mark.
