How To Generate 13 Digit Number From Two Data Colu

Hi

I have two below datacolumns

'code'- varchar 255 (Unique number) data : chr456Umx
'Packs'- integer data : 6

Is it posible to generate 13 digit number using the above two columns,
The reason is if I run the procedure I will get same 13 digit all the time depending on the above two colums


below is the sample procedure I am using


CREATE PROCEDURE AMZSelCen
@imglink nvarchar(255)

AS

Select code as sku,
PdtBarCode as [standard-product-id],
'EAN' as [product-id-type],

--generate 13 digit number

make+' '+model+' ' +', Price for '+cast(NumPacks as varchar(8)) +' '+'Packs' as title,
make as manufacturer,'

from tablename
where ......
