Notwithstanding any other provision of law, if a certificate or instrument evidencing shares of stock, or rights to purchase or subscribe to shares of stock, is in the custody of a clearing corporation or of a custodian subject to the instructions of a clearing corporation, title to any such certificate or instrument or to any interest therein and to the shares or rights evidenced by such certificate, instrument or interest may be transferred by making entries on the books of the clearing corporation reducing the account of the transferor by the number of shares or rights transferred and increasing the account of the transferee by such number of shares or rights. A transfer of title so made shall have the same effect as if the transferor had delivered to the transferee a certificate or instrument evidencing the shares or rights transferred, duly indorsed in blank.
