def is_valid_israeli_id_num(id_num : str):
    if len(id_num) == 8:
        id_num = '0' + id_num
    if len(id_num) != 9:
        return "Invalid input!"
    digit_sum = 0
    for i in range(len(id_num) - 1):
        new_value = int(id_num[i]) * (i % 2) + 1  # multiply odd indexed digits by 1, and even indexed digits by 2
        digit_sum += (new_value % 10) + (new_value // 10)  # accumulate the new value's digital root

    # the check digit is the difference between the accumulated sum,
    # and the next number that is a multiple of 10:
    expected_check_digit = str((-digit_sum) % 10)  
    
    return expected_check_digit == id_num[-1]
