A number of research have vs A number of research has

Neither of these phrases is correct. The correct form should be 'a number of research studies have.' 'Research' is an uncountable noun, so it does not take the plural form 'researches.' Instead, it should be followed by a plural noun like 'studies' to match the plural verb 'have.'
