Where is a sequence dependency to table stored within data dictionary?

Table could have dependency to a sequence in its DDL.

In case of dropped sequence inserts into table will fail due to missing sequence.

I would like to check tables for which inserts will fail due to missing dependency.

Where is the sequence dependency between table and sequence strored within data dictionary?

Simple example:

create sequence seq1;

create table tab1

( col1 number default seq1.nextval not null,

  col2 number generated by default as identity not null

);

Developer has created sequence and table like above, inserted many rows into table, later wanted to rename sequence, dropped sequence seq1, created sequence seq2.
