Hi bluedevil
 I hav checked these on Mouser.

TL074CN - OK
LM311P - OK
TLE2072CP - OK
TL712CP  - OK

NOTE!
I trided to order some TLE2072 from China once.
They were all fakes and did not even come close to the specs for TL072.

I can attest to this, especially when ordering electronic components from aliexpress. They have independent sellers there and a lot of fakes. Be especially wary if a deal seems to good to be true. It usually is.
That being said, there are legit bargains that can be had there as well (aliexpress). NOTE: some sellers sell used parts but do not say they have been desoldered. So, from my experience aliexpress is a mixed bag. Buyer beware... unsure of other Chinese vendors myself. Pretty sure ordering from amazon will yield similar results as with aliexpress as far as quality or lack thereof.
BTW don't buy resistors there at aliexpress. Cheaply made and very thin leads. Tolerances are ok, but .... cannot be used in solderless beadboards for prototyping. Leads are just too thin.

@KetiLO and @zedd151
Thank you for replies. I understand that mouser is more reliable? I have bought some arduino and arduino components before and they were all good btw.

Mouser and other companies specifically selling electronic components should be fine, imo. Buying from oversees has been a mixed bag (some good, some bad) for me. Of course Mouser et. al., would be more expensive but would have some semblance of quality to what they are selling as opposed to aliexpress.
