How to check if a string is a product SKU?

Question

Algorithms

Good afternoon. Has anyone come across a task like: "Determine that string X is a product SKU?". An article is not an article for a specific given range of goods, but an abstract article in a vacuum. Those. article can be:

• FX-200-7-D
  
• 01002099
  
• AB001D
  
• TPG_53000_M2
  
• etc., the list is endless, see examples on trading platforms like Yandex.Market
  

The formalization of the task, instead of a ready piece of the code interests. But if there is a code in any language, I will be grateful for it. And yes, I understand that the statement of the problem is more than vague, I myself do not like it.

Answer 1

It seems to me that this is impossible to do. The article can be any set of letters and numbers. There is no general coding rule.
The only way I see is to have a database of articles and refer to it.

Answer 2

I would start with an understanding of what article patterns exist in general (maybe they can be segmented by product type, for example, kettles, electric stoves, macbooks).

Answer 3

Create an index on articles and make a selection on this field. This is one of the fastest methods. Another method is to systematize the suppliers and call an article check for each.
