6th place contains only 6 digits.
7th place contains only one ‘-‘.
8th place contains only 1 digit.

sth like this: 0010-155-072-120410-0

I use this but not work: '/[1-9]{4}-[1-9]{3}-[1-9]d{3}-[1-9]{6}-[1-9]{1}/'

Answer 1

'/^\d{4}-\d{3}-\d{3}-\d{6}-\d$/'

Use this. In your example you have extra "d" character at the middle.
Also don’t forget to include start and end symbols to avoid extra characters at begining and at the end.
