See this site for info on how they are calculated : https://teppen.io/2018/06/23/aws_s3_etags/
Not sure if anyone ever checks ETags in this way, the AWS docs say that in case of a multipart upload the ETag should be considered as an opaque value so it is probably not necessary to it like described in the link. It would also be quite hard as the MD5 sums of individual parts has to be added to the metadata database (currently it only stores sha256 sums of blocks, which are themselves chunks of the uploaded parts).
