+# CheckReg
+It can check whether a given email or phone number has been registered in websites.
+
+## Install
+
+```shell
+pip install checkreg-zhongpu
+```
+
+## Supported Websites
+
+### [dangdang](http://www.dangdang.com/)
+
+```python
+from checkreg import dangdang
+x = dangdang.check_phone('138xxxxxxxx')
+```
+
+The result `x` is a dictionary. For example,
+
+```python
+{'statusCode': '0', 'errorCode': '0', 'errorMsg': None, 'if_exist': True, 'cust_id': '744073637'}
