-任务：
+For each number list of 6-digit [SEDOL](https://en.wikipedia.org/wiki/SEDOL "wp: SEDOL")s, calculate and append the checksum digit. That is, given the input string on the left, your function should return the corresponding string on the right:
 
-对于6位[SEDOL](https://en.wikipedia.org/wiki/SEDOL "wp：SEDOL")的每个数字列表，计算并附加校验和数字。
+<pre>
+710889 => 7108899
+B0YBKJ => B0YBKJ7
+406566 => 4065663
+B0YBLH => B0YBLH2
+228276 => 2282765
+B0YBKL => B0YBKL9
+557910 => 5579107
+B0YBKR => B0YBKR5
+585284 => 5852842
+B0YBKT => B0YBKT7
+B00030 => B000300
+</pre>
 
-也就是说，给定左侧的输入字符串，您的函数应返回右侧的相应字符串：
-
-```
- <pre> 710889 => 7108899 B0YBKJ => B0YBKJ7 406566 => 4065663 B0YBLH => B0YBLH2 228276 => 2282765 B0YBKL => B0YBKL9 557910 => 5579107 B0YBKR => B0YBKR5 585284 => 5852842 B0YBKT => B0YBKT7 B00030 => B000300 </pre> 
-```
-
-还要检查每个输入是否正确形成，尤其是对于SEDOL字符串中允许的有效字符。您的函数应在无效输入时返回`null` 。
+Check that each input is correctly formed, especially with respect to valid characters allowed in a SEDOL string. Your function should return `null` on an invalid input.
 
 # --hints--
 
-`sedol`是一个功能。
+`sedol` should be a function.
 
 ```js
 assert(typeof sedol === 'function');
 ```
 
-`sedol('a')`应该返回null。
+`sedol('a')` should return null.
 
 ```js
 assert(sedol('a') === null);
 ```
 
-`sedol('710889')`应返回'7108899'。
+`sedol('710889')` should return '7108899'.
 
 ```js
 assert(sedol('710889') === '7108899');
 ```
 
-`sedol('BOATER')`应该返回null。
+`sedol('BOATER')` should return null.
 
 ```js
 assert(sedol('BOATER') === null);
 ```
 
-`sedol('228276')`应该返回'228276'。
+`sedol('228276')` should return '2282765'.
 
 ```js
 assert(sedol('228276') === '2282765');
