literatura.mk lists ISBN as the mal-formed one. It is undoubtedly a mistake, however, it is kind of a deep mistake because the check digit (3) was calculated correctly using 948-608-289-755. Assuming 978-608-289-755 is correct, the right check digit is 4 (978-608-289-755-4).
2024-12-09: Found the correct ISBN: 978-608-259-755-3; removing the incorrect, corrected on, but will leave the mistaken one for record keeping purposes
