算法在附件中，百度得来，问题是水平太低，求老师帮忙写个代码，谢谢。

我能想到的办法是建数据表去查询，再计算，可能比较笨，有没有可能全写在代码里？

红袍老师，还有一种特殊情况：

如果余数为10，校验码为字母X

比如：LFP83ACCXD1D99699，4楼的算法不灵了

代码看了个大概，改了改就行了：

Dim q() As Integer = {8,7,6,5,4,3,2,10,0,9,8,7,6,5,4,3,2}
Dim v() As Integer = {0,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,1,2,3,4,5,7,9,2,3,4,5,6,7,8,9}
Dim w() As String = {0,1,2,3,4,5,6,7,8,9,"A","B","C","D","E","F","G","H","J","K","L","M","N","P","R","S","T","U","V","W","X","Y","Z"}
Dim num As String = "LFP83ACCXD1D99699"
Dim sum As Double = 0
For i As Integer = 0 To num.length - 1
    Dim s As String = num(i)
    sum += v(array.indexOf(w,s.ToUpper)) * q(i)
Next
Dim n9 As String = IIF(sum Mod 11 = 10, "X", sum Mod 11)
msgbox(n9)
