JS檢驗用戶輸入的銀行卡號的合法性，搜索后都說采用Luhn算法進行校驗，Luhn算法介紹可見這位博友https://www.jianshu.com/p/193...，JS代碼實現(xiàn)如下：

function acount_check(cardNum) {
  if(!cardNum) return false;
  let len = cardNum.length;
  let carNumArr = Array.from(cardNum.slice(0,len));
  let tem = 0;
  for(let i = len-2;i>=0;i-=2){
    tem = parseInt(cardNum[i])*2;
    carNumArr[i] = Math.floor(tem/10) + tem%10;
  }
  let result = 0;
  carNumArr.forEach(val => {
    result+=parseInt(val);
  })
  return result%10 == 0;
};

經(jīng)檢測，部分銀行卡號并不符合上面的算法規(guī)則，檢測數(shù)據(jù)為下述鏈接：https://www.qusocha.com/bank/1/
如：該卡號返回false:(6217003480001296493),在線銀行卡號查詢網(wǎng)站http://www.cardcn.com/search....查詢后，確實存在該卡號。請問各位碼友們有什么好的解決方案碼？
