  sum = (0..11).inject(0) do |sum, i|
    sum + cnpj_root[i] * factor[i]
  end

  first_validator = sum % 11
  cnpj_root << first_validator = first_validator < 2 ? 0 : 11 - first_validator

  # calculate second digit

    sum + cnpj_root[i] * factor[i]
  end

  second_validator = sum % 11
  (cnpj_root << second_validator = second_validator < 2 ? 0 : 11 - second_validator).join
