it helps some times You can use alternations to define different conditions and use this regex,
code :
^[a-zA-Z]{2}(?:9[0-9]{7,8}|[0-5][0-9]{8}|[6-8][0-9]{7})$
const arr = ['ab91234567','ab912345678','ab9123456789','sd012345678','sd0123456789','df71234567','df712345678']

arr.forEach(x => console.log(x + " --> " + /^[a-zA-Z]{2}(?:9[0-9]{7,8}|[0-5][0-9]{8}|[6-8][0-9]{7})$/.test(x)))

will be helpful for those in need You can use a zero-width positive assertion to solve this. Here's the regex, and I'll deconstruct it below.
code :
/(?=.*[A-Za-z0-9])[A-Za-z0-9, .!@#$%^&*()_]{3,25}/

To fix the issue you can do Just by looking at it, I'd say the second method is faster.
However, I made a quick non-scientific test, and the results seem to be inconclusive:
regex for validating only alphanumeric characters full stop, comma, colon, and semicolon

var regexp = new RegExp(/^[a-zA-Z0-9.,:;]+$/);

this will help I need to match a string under the following conditions using Regex in C#: , You might try this which I made as close as possible to your regex:
code :
^(?=.*(?:best [0-9]|[0-9] best)).*$
^(?=.*(best [0-9]|[0-9] best)).*$
