Formal:
* Ai-je raison? (This is the most literal translation and the most formal option)
* N'ai-je pas raison? (This is a more assertive way of asking the question)
Informal:
* Tu ne trouves pas? (This literally means "Don't you think so?" but it's a common way to ask if someone agrees)
* J'ai raison, non? (This literally means "I'm right, right?")
* C'est ça, non? (This literally means "That's it, right?")
* Vous ne trouvez pas? (This is a more formal version of "Tu ne trouves pas?")
Note: The use of "vous" or "tu" will depend on your level of formality and your relationship with the person you are speaking to.
It's also important to note that the French language often uses a more indirect approach than English when it comes to asking questions. Instead of directly asking "Am I right?", you might find it more common to express your opinion and then ask the other person to confirm. For example:
* Je pense que... (I think that...) Tu ne trouves pas? (Don't you think so?)
* C'est mon avis... (That's my opinion...) Qu'en penses-tu? (What do you think?)
