Why this transaction is valid?

Question

Its output script is "OP_HASH160 da1745e9b549bd0bfa1a569971c77eba30cd5a4b OP_EQUAL".

Its input script is "51".

I verified the transaction manually but it failed. Why the transaction was accepted and confirmed?

The evolved stack is as below. What's wrong? 628850cb844fe63c308c62afc8bc5351f1952a7f = RIPEMD160(SHA256(1))

The transaction is valid. This golang code gives the correct result.

You need to HASH160 51, not 1.

Additionally, make sure you run the hash on 0x51, not "51" or int(51).

Thank you for your answer, Raghav! I cannot access the golang code on github. Could you please update the url link? Thanks again.

@JDoe That's odd. Seems to work for me. Here's the same code on pastebin
