You can check this for weapons by going into the encyclopedia (book icon in the top right). Then click gear & search the item. In the bottom of the menu it has a button for adds.
Under adds there are two sets of addons, one set starts with "fixed". Weapons will only ever have 1 fixed add. The rest of the adds can pop multiple times. Claws, daggers etc have int as their fixed add whereas bows have int under the random category.
