全国组织机构代码的基本组成：由8位数字（或大写字母）和1位数字（或大写字母）组成；如下图

校验代码的实现如下：

/** * Desc: 全国组织机构代码 校验 * Created 2016/6/6. */public class Regex_OrganizationCertificate {    private static String str1 = "D2143569-X";// 测试    private static String str2 = "74371976-1";// 测试    private static String str3 = "L1832212-3";// 测试    private static String isOrganizationCertificate = "true";    private static String error_OrganizationCertificate ="输入的机构代码错误，请核对后再输！";    private static String error_OrganizationCertificate_num ="输入的机构代码位数不对，请核对后再输！";    /**     * 加权因子     */    private static int power[] = {3,7,9,10,5,8,4,2};    public static void main(String[] args) {        String temp = str2;        System.out.println(temp);        isOrganizationCertificate(temp);    }    /**     * 判断机构代码是不是有效的     * @param organizationCertificate     * @return     */    public static String isOrganizationCertificate(String organizationCertificate) {        String temp = organizationCertificate.toUpperCase();        if (temp.contains("-")) {            temp = temp.replace("-", "");            System.out.println(temp);        }        if(temp.length()!=9){            System.out.println(error_OrganizationCertificate_num);            return error_OrganizationCertificate_num;        }        // 获取前面8位        String pre8 = temp.substring(0,8);        char[] pre8chars = pre8.toCharArray();// 0~z;        // 获取校验码        String code = temp.substring(8,9);        boolean isCode = isCode(code,sum(pre8chars));        System.out.println(isCode?isOrganizationCertificate:error_OrganizationCertificate);        return isCode?isOrganizationCertificate:error_OrganizationCertificate;    }    /**     * 求和     * @param bit     * @return     */    private static int sum(char[] bit){        int sum = 0;        for(int i=0;i<bit.length;i++){            int intTemp = bit[i]>'9'?(bit[i]-'A'+10):Integer.parseInt(bit[i]+"");            System.out.print(" "+intTemp);            sum +=intTemp*power[i];        }        System.out.println();        System.out.println(sum);        return  sum;    }    /**     * 判断机构代码的校验码和计算出的校验码是否一致     * @param a     * @param b     * @return     */    private static boolean isCode(String a,int b){        String codeTEmp = (11- b%11)==10?"X":(11- b%11)==11?0+"":(11- b%11)+"";        System.out.println(codeTEmp);        return a.equals(codeTEmp);    }}
