The DES Calculator online tool (https://emvlab.org/descalc/) helps to calculate the key (using encrypt mode = DES-CBC). Cipher block chaining (CBC) is a mode of operation for a block cipher (one in which a sequence of bits is encrypted as a single unit or block with a cipher key applied to the entire block). Cipher block chaining uses what is known as an initialization vector (IV) of a certain length.
