Yes,  failing one subject in 12th grade but passing overall and completing graduation in first division will likely make you eligible for the SSC CGL exam and document verification. The Staff Selection Commission (SSC) requires a candidate to have passed the 12th class examination from a recognized board. As long as you have a passing certificate for 12th standard, even with a fail in one subject, you meet the basic eligibility criteria.

The SSC CGL emphasizes your graduation degree for most posts. Since you have a first-class graduation, it strengthens your application.

While the general eligibility mentions passing 12th, some specific posts within the SSC CGL might have stricter requirements. Double-check the notification for the specific post you're interested in to ensure there are no additional requirements regarding class 12th subjects or marks.

During document verification, the SSC might ask about the failed subject in 12th. Be prepared to explain the situation honestly. Having a first-class graduation demonstrates your academic ability overall.
