Take a look at the snippet.

inputVal === "123-21" || inputVal === "154-2" || inputVal === "1235-1" checks if the inputVal-variable is equivalent to "123-21", "154-2" or "1235-1".

function getInputValue() {
  var inputVal = document.getElementById("myInput").value;
  if (inputVal === "123-21" || inputVal === "154-2" || inputVal === "1235-1") {
    document.getElementById("alertaValidacion").innerHTML = "El Producto que usted Compro es Original.";
    document.getElementById("alertaValidacion").className = "alert-success";
  } else {
    document.getElementById("alertaValidacion").innerHTML = "El producto que adquirio No es Original. podria ser una falsificacion";
    document.getElementById("alertaValidacion").className = "alert-danger";
  }
}

getInputValue();

.alert-success {
  color: green;
}

.alert-danger {
  color: red;
}

<input id="myInput" type="text" value="123-21" oninput="getInputValue()"/>
<p id="alertaValidacion"></p>

The first if statement you have split up your statement like so

if (inputVal === "123-21" || inputVal === "154-2" || inputVal === "1235-1"){
