Oh.. is the the whole "9059 Ser: F8R8WF1290810473" part in one cell? And, you are trying to pull the last 16 digits? And, most importantly, are the consistent in 16 digits for the last part?
If that's the case, apply the following formula.
Once completed in that cell, just drag it down and it should do the job.
However, if you see inconsistent result (part number being cut off etc..) you may have a few extra spaces in the beginning or end or that referencing cell. If that's the case, enter =trim(referencing cell) upon inserting an extra column just right of the referencing column, which should eliminate all the unwanted spaces. Then, in insert another column next to it and apply the "=right" formula mentioned above.
in each cell there will be "Installed: 9059 Ser:" followed by a 16 digit reference number. It is this reference number that i need to extract. In each cell, the format will not be the same, the "Installed: 9059 Ser:" will be at different places within the cell information, hence =right(A1,16) will not work. This is why i figured fairwinds logic was good, if i can pull out the 16 characters after the Installed: 9059 Ser: then i would be gold.
