I had to search to find out what a CPF is, but I think I figured it out and found some code.

Try placing this in a javascript column and set the p1 parameter to the column that contains your CPF.

```auto
if (p1!=null){
return validarCPF(p1);
} else {
return false;
}

function validarCPF(cpf) {	
	cpf = cpf.toString().replace(/[^\d]+/g,'');	
	if(cpf == '') return false;	
	// Elimina CPFs invalidos conhecidos	
	if (cpf.length != 11 || 
		cpf == "00000000000" || 
		cpf == "11111111111" || 
		cpf == "22222222222" || 
		cpf == "33333333333" || 
		cpf == "44444444444" || 
		cpf == "55555555555" || 
		cpf == "66666666666" || 
		cpf == "77777777777" || 
		cpf == "88888888888" || 
		cpf == "99999999999")
			return false;		
	// Valida 1o digito	
	add = 0;	
	for (i=0; i < 9; i ++)		
		add += parseInt(cpf.charAt(i)) * (10 - i);	
		rev = 11 - (add % 11);	
		if (rev == 10 || rev == 11)		
			rev = 0;	
		if (rev != parseInt(cpf.charAt(9)))		
			return false;		
	// Valida 2o digito	
	add = 0;	
	for (i = 0; i < 10; i ++)		
		add += parseInt(cpf.charAt(i)) * (11 - i);	
	rev = 11 - (add % 11);	
	if (rev == 10 || rev == 11)	
		rev = 0;	
	if (rev != parseInt(cpf.charAt(10)))
		return false;		
	return true;   
}

```
