判断身份证号输入是否正确

1、首先我们可以在身份证的后面一列插入辅助列C列

2、在C3中输入=IFERROR(IF(TEXT(IF(MOD(12-(MID(B3,1,1)*7+MID(B3,2,1)*9+MID(B3,3,1)*10+MID(B3,4,1)*5+MID(B3,5,1)*8+MID(B3,6,1)*4+MID(B3,7,1)*2+MID(B3,8,1)*1+MID(B3,9,1)*6+MID(B3,10,1)*3+MID(B3,11,1)*7+MID(B3,12,1)*9+MID(B3,13,1)*10+MID(B3,14,1)*5+MID(B3,15,1)*8+MID(B3,16,1)*4+MID(B3,17,1)*2),11)=10,"X",MOD(12-(MID(B3,1,1)*7+MID(B3,2,1)*9+MID(B3,3,1)*10+MID(B3,4,1)*5+MID(B3,5,1)*8+MID(B3,6,1)*4+MID(B3,7,1)*2+MID(B3,8,1)*1+MID(B3,9,1)*6+MID(B3,10,1)*3+MID(B3,11,1)*7+MID(B3,12,1)*9+MID(B3,13,1)*10+MID(B3,14,1)*5+MID(B3,15,1)*8+MID(B3,16,1)*4+MID(B3,17,1)*2),11)),0)=MID(B3,18,1),"对","错"),"")
