Better: The validity of these results is unclear.

'Validity' is the singular subject, so it takes the singular verb 'is,' even when followed by a plural noun.

यहाँ मुख्य subject 'validity' singular है, इसलिए plural 'results' के बाद भी verb 'is' आएगा।

Not natural: We need to check the validity this document.

Better: We need to check the validity of this document.

Use 'of' after 'validity' to identify the document or claim whose validity is being checked.

जिस document या claim की validity जाँची जा रही है, उसका नाम बताने के लिए 'validity' के बाद 'of' लगाएँ।
