    If you only want to allow chars a-z A-Z or digits:

    ^(?=[a-zA-Z]*d)(?:d*[a-zA-Z]){9}[a-zA-Zd]*$

    Explanation

    • ^ Start of string
    • (?=[a-zA-Z]*d) Assert at least a single digit
    • (?:d*[a-zA-Z]){9} Match at least 9 times a char a-zA-Z preceded by optional digits
    • [a-zA-Zd]* Match optional chars a-z A-Z or digit
    • $ End of string

    The following matched the requirements, I don’t know if it generally valid as you only gave three examples:

    [a-zA-Z]*[d]{1}[a-zA-Z]*

    Does this work (JS):

    let a = "abcedf123.f4ada";
let b = [...a.matchAll(/[a-zA-Zd]{9,}/g)];
console.log(b);
