You're doing a call to getValues every row, that eats a lot of performance.
It is better to do one big call to have all the data and then go through it sequentially.

var s = SpreadsheetApp.getActiveSheet();
var data = s.getRange(1,4, s.getLastRow()).getValues();

var toAddArray = data.map(function(row, i) {
  var Valus = row[0].toString();
  var newznach = Valus.
    replace(/\-/g, "").
    replace(/[0-9][0-9][0-9][0-9][0-9][a-zA-Zа-яА-Я][a-zA-Zа-яА-Я]/g, "").
    replace(/[a-zA-Zа-яА-Я][a-zA-Zа-яА-Я]/g, "");

  return [i.toFixed(0), Valus, newznach];
});
