The first thing is to point out that the concept of ISI is no longer used. Several years ago, the databases that index and were ISI today belong to the Web Of Science Core Collection (WoS) of the Clarivate Analytics company. To know the journals that are part of WoS you can access the following link http://mjl.clarivate.com/
As for the journals indexed in Scopus you can access the following link to know them https://www.scimagojr.com/
Finally, note that Elsevier is the company that owns Scopus, therefore all the journals that are part of Elsevier are part or are indexed in Scopus
