代码校验位及其计算方法

Code Check Digit and its Calculation

在代码的输入、代码的检查和代码的真伪判别方面，校验位起着重要作用，因此，常常在代码结构中加入校验住。“加权取余”方法是一种常用的校验位计算方法，改变其权因子可以得到不同的计算方式，因此，被广泛应用于社会和科学技术等各个领域。

Enter the code, code inspection and determine the authenticity of the code, the check digit plays an important role, therefore, often append the check digit to code structure. ＂Weighted to take remainder＂ method is a check digit calculation methods commonly used to change the weight factor can be calculated different ways, therefore, is widely used in society and science and technology fields.
