Most of Mandeleev's suggestion were based
on assumption. There were no experimental proof for his suggestions. Example, he changed the atomic mass of Be to 9 and placed above Mg in his table which is correct, as the properties of Be and Mg were same. Later these elements were named as alkaline earth metal.
So Mandeleev's suggestion was correct.
