Autocalculate Age from Identity Card Number

My 1st uploaded file might be with wrong formula to calculate the age that's why it return for 101 age instead of 1 year old of age. It should return as 1 year old of age.
There is no minimum age in here (Malaysia) to make Identity Card Number.
Rarely people lives more than 100 years of age in here.
e.g. 110106105717 means the birth date 06/01/2011 (1st 6 numbers) rarely to see people born on the year 1911 with ID number anymore.
Thank you everybody for your help.
I must add in the DOB next to Identity Card Number and to get the actual Age (Below 100 years old).
Thanks again
