Postgresql regex match by end of string

I have a table like this :

> create table sample(id int, identity varchar(20)) ;
> insert into sample (id,identity) values (1,'9822');
> insert into sample (id,identity) values (2,'129822');
> insert into sample (id,identity) values (3,'ABCD9822');
> insert into sample (id,identity) values (4,'1234');

------------------------
> select * from sample ;
 id | identity 
----+----------
  1 | 9822
  2 | 129822
  3 | ABCD9822
  4 | 1234
(4 rows)

I have a string like 0987129822 .
how to select on database to fetch all identities ends matches by this string ?
I need this result :

 id | identity 
----+----------
  1 | 9822
  2 | 129822

Note : maybe this question duplicated , but i can not understand what keyword should i search on google .
