I had a look at wikipedia article on MEID format and it gave required information. You want to convert 7700 to 10057472. 99000124base16 = base10. 997700base16 = 10057472base10. Concatenating base10 numbers gives 10057472. Theory: Split the hex number into 2 parts, length 8 and length 6.

According to Wikipedia

For the decimal format the first three digits are the decimal representation of the first 8 bits (between 000 and 255 inclusive) and the next 8 digits are derived from the remaining 24 bits and will be between 00000000 and 16777215 inclusive

The above gives the same output with that page, however, I don't know anything about an ESN.
