How the "check digit" in the Taxpayer Identification Number is computed

Requested from BIR by J. Ibay at 12:07 AM on Jan 04, 2022.
Purpose: Information dissemination, to be shared to a small group of people
Date of Coverage: 01/03/2022 - 01/03/2022
Tracking no: #BIR-149240649109

Ibay 12:07 AM, Jan 04, 2022 

An NTRC journal from 2014 mentions that the ninth digit (the digit before the branch code) of a taxpayer identification number (TIN) is a check digit.

if that is the case, how is that computed? (The formula)

or if that is not the case, is the ninth position sequential?

With regard to personal data, NO TIN of a taxpayer shall be disclosed. Only the formula in computing the purported check digit, if that is the case.
