集装柜 柜号验证

标准柜号构成基本概念：采用ISO6346（1995）标准。

标准集装箱箱号由11位编码组成，包括三个部分：（4位英文字母+6位数字+1位校验码）

1、 第一部分由4位英文字母组成。前三位代码 (Owner Code) 主要说明箱主、经营人，第四位代码说明集装箱的类型（所有海运柜子的第四个字母，都是U，是用于海运集装箱的代号）。列如CBHU 开头的标准集装箱是表明箱主和经营人为中远集运。

2、 第二部分由6位数字组成。是箱体注册码（Registration Code），用于一个集装箱箱体持有的唯一标识。

3、 第三部分为校验码（Check Digit）由前4位字母和6位数字经过校验规则运算得到，用于识别在校验时是否发生错误。即第11位数字。

根据校验规则箱号的每个字母和数字都有一个运算的对应值。箱号的前10位字母和数字的对应值从0到Z对应数值为0到38，11、22、33不能对11取模数，所以要除去

第N位的箱号对应值再分别乘以2的N－1次方 （N=1，2，3………..10）

例如：箱号为CBHU3202732的集装箱它的第1位代码为C，

它的代码值=代码的对应值×2的0次方 =13×1=13。

类推第2位代码为B

它的代码值=代码的对应值×2的1次方 =12×2=24

以此类推得到箱号前10位代码的代码值。

将前10位的代码值乘积累加后对11取模

箱号为CBHU3202732的集装箱前10位箱号的代码累加值=4061，取11的模后为2，就是这个箱号第11位的识别码的数值。

公式

校验码S=∑Ci*2

以此类推，就能得到校验码。
