Short answer. Generally yes. Article 1608 lets you, as the seller under a pacto de retro sale, bring a redemption action against every later possessor whose right traces back to the original buyer, even if your right to repurchase went unmentioned in that later sale, subject to Mortgage Law and Land Registration Law protections for third persons.
What the law says
The vendor may bring his action against every possessor whose right is derived from the vendee, even if in the second contract no mention should have been made of the right to repurchase, without prejudice to the provisions of the Mortgage Law and the Land Registration Law with respect to third persons.

Your right follows the property, not just the original buyer
Article 1608 addresses exactly the situation where the buyer under a sale with right to repurchase later transfers the property to someone else. It says the seller may bring his redemption action against every possessor whose right is derived from the original buyer. This means your right to repurchase is not automatically defeated simply because the property changed hands after the original sale; you can generally pursue redemption against whoever currently holds a right traced back to that buyer.
It does not matter if the new deed is silent about your right
Article 1608 specifically addresses the concern that the second contract, between the original buyer and the new possessor, might not mention your right to repurchase at all. The article says your action can proceed against that later possessor even if no mention should have been made of the right to repurchase in that second contract. Silence in that later deed about your right does not, by this article, defeat your ability to bring the redemption action against the current possessor.
The important qualification: registration law protections
Article 1608 is not unlimited. It expressly operates without prejudice to the provisions of the Mortgage Law and the Land Registration Law with respect to third persons. This means the outcome can still depend on registration: a subsequent buyer who is protected under those registration laws as an innocent third party may stand on different footing than one who is not, since those laws have their own rules about what a buyer relying on a clean title is entitled to assume.
Why this matters when you exercise the right
Because your ability to redeem against a later possessor interacts with registration law, the practical picture depends heavily on how the original pacto de retro sale and your right to repurchase were reflected, or not reflected, in the public records at the time the property changed hands again. This is where the general rule of Article 1608 and the registration-law qualification it carries have to be read together to work out where you actually stand against the current possessor of the land.
