If you mouse over that number you will see a number that is much longer.  The longer number is a UUID number, also sometimes referred to as a Key.  It is the number the servers which store your inventory assigns to inventory items to keep track of them. Avatars also have key's or UUID numbers that servers use to identify a specific avatar.  Scripts  use these numbers too to identify specific avatars or items.

You can find any non object items UUID by right clicking it in your inventory and selecting Copy UUID then pasting it where you can paste text like a notecard or chat.  For objects, you must rez them in world and go to Edit, the click the Copy Key button and paste it.

If the transaction  involves a transfer of Lindens, or you "buy" for zero lindens, such as a purchase you made in world, you will see the items name in the description field.  If it was a marketplace purchase you will need to use the marketplace order number to look it up in your order history on the marketplace where the name will be given. 

Transactions that do not involve buying or selling, such as when you give something, or receiving something for free by passing it to another avatar or receive something from a scripted object, do not have descriptions and you can not search your inventory by UUID using some viewers (although some older third party viewers can do this).  It is presumed that you know what they were.  Your transaction history is an reconciliation and accounting of the money in your LIndens account.  Passing inventory does not involve Lindens and therefore the name of the item is not recorded.
