Malformed UUID Error Handling

Hello, I have a function that was written poorly as follows

export const IMAPtoUUID = (data: string): UUID => {
  console.log(`Converting IMAP ID to UUID: ${data}`);
  const padded = data.padEnd(32, '0');
  let result = `${padded.slice(0, 8)}-${padded.slice(8, 12)}-${padded.slice(12, 16)}-${padded.slice(16, 20)}-${padded.slice(20)}` as UUID;
  console.log(`Converted UUID: ${result}`);
  return result;
};

Converting IMAP ID to UUID: msg-f:1837281717662508024
Converted UUID: msg-f:18-3728-1717-6625-080240000000

But when that value is sent to my DB, no error is thrown, instead it shows
197f55fc-e597-e3f8-0000-000000000000

I have tried reverse engineering myself but I was unable to determine how this fix occurs. This is important because I would like to implement a UUIDtoIMAP function that reverses this, but cannot until I know the underlying algorthim.
