java 代码

public static char doVerify(String id) {
        char pszSrc[] = id.toCharArray();
        int iS = 0;
        int iW[] = { 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2 };
        char szVerCode[] = new char[] { '1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2' };
        int i;
        for (i = 0; i < 17; i++) {
            iS += (int) (pszSrc[i] - '0') * iW[i];
        }
        int iY = iS % 11;
        return szVerCode[iY];
    }
