I do not want it to delete patterns like fraction:
1/2  or 3-1/2 or 3 1/2 or 16/32


I need this regex to work for the following patterns BUT NOT in the same regex call
before:
LU250/40/H/ECO
LU310/H/ECO
CMH39/MR16/UL93\SP
CMH39/MR16/UL93/FL
CMH39/MR16/UL93WFL
F28T8/XL\SPX35\ECO
CMHi\23P38/FL/ECO

After:
LU25040HECO
LU310HECO
CMH39MR16UL93SP
CMH39MR16UL93FL
CMH39MR16UL93WFL
F28T8XLSPX35ECO
CMHi23P38FLECO
