Are you sure you're taking the correct number for coding? I don't own a diesel, never have and never will, so I don't have own experience, but from what I've found online the code to use is 16 characters in hexadecimal, that's why it contains only digits from 0 to 9 and letters from A to F included.
What you've showed on the photo is not the correct code.
The first 6 characters are the serial number of the injector (so should be unique), the last 4 are the parameters of this particular injector.
It's calles IMA Denso.
From what I could see it, for refurbished injectors the new IMA code should be on the sticker and on the certificate.
