-[国际银行账号（IBAN）](https://en.wikipedia.org/wiki/International_Bank_Account_Number)是一种国际商定的识别跨国界银行账户的方法，降低了传播[抄写错误的](https://en.wikipedia.org/wiki/Transcription_error)风险。 IBAN最多包含34个字母数字字符：
+The [International Bank Account Number (IBAN)](https://en.wikipedia.org/wiki/International_Bank_Account_Number) is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of propagating [transcription errors](https://en.wikipedia.org/wiki/Transcription_error).
 
--   首先是两个字母的ISO 3166-1 alpha-2国家代码
--   然后是两个校验位，和
--   最后是国家特定的基本银行帐号（BBAN）。
+The IBAN consists of up to 34 alphanumeric characters:
 
-通过检查数字，即使在提交交易之前，也可以对银行帐号进行健全性检查以确认其完整性。编写一个以IBAN字符串作为参数的函数。如果有效则返回true。否则，返回false。
+<ul>
+  <li>first the two-letter ISO 3166-1 alpha-2 country code</li>
+  <li>then two check digits, and</li>
+  <li>finally a country-specific Basic Bank Account Number (BBAN).</li>
+</ul>
+
+The check digits enable a sanity check of the bank account number to confirm its integrity even before submitting a transaction.
+
+# --instructions--
+
+Write a function that takes IBAN string as parameter. If it is valid return true. Otherwise, return false.
