I have a code in JS which is pushing value to a comma separated string if that value do not exist in the list.
I want the similar thing into SQL Server also.

What I have tried:

I am able to make comma separated list into column with values, i am converting list into a temp table and checking one by if new numbers exists.

Is there any better way to perform this? Please help me finding.

It's generally a bad idea to store comma separated lists in SQL at all, yopu woudl probably be better off with a second table and a foreign key.
But...

SQL

UPDATE MyTable SET MyColumn = MyColumn + ',' + 'My new item' WHERE MyIDColumn=MyIDValue

Takign one back out again is a much, much harder process - which is one of the reasons why the second table is a much better design.
