The direct answer
Compare the exact sample name, lot identifier, and report code across the report and the records you are reviewing. A matching compound name alone does not verify a lot match. COA7920 prints the other fill's lot number: RET-20260811-02 belongs to the 15mg fill, COA7918. The site's COA record explains the resolution: the production lot register identifies the 30mg fill as RET-20260811-01, and the vials carry that label. Keep both the original mismatch and its documented resolution visible.
Keep these distinctions
- A sample name, a lot number, and a report code are different identifiers.
- A link resolving to a report is different from a verified lot match.
What this does not establish
- The original certificate still prints RET-20260811-02; the site record documents the correct 30mg lot as RET-20260811-01 and says a corrected certificate has been requested.
- The production-register and vial-label explanation is attributed to the site's COA record. No physical container, lot register, custody history, or issuer response was independently examined here.
Follow the detail
Compare separate identifiers
The inspected COA7919 presents sample name, lot number, and web verification code in separate places. Each field answers a different document question: the material label, the claimed sample lot, and the report identifier. A useful comparison keeps these values separate rather than relying on a filename or a familiar name. This answer has not examined a physical container or its custody history, so even a matching set of visible fields would be a document match within the records inspected.

Fields are visually present. The comparison method is an editorial reading procedure and is explicitly limited to document identity.
Follow the mismatch through to its resolution
The local COA7920 PDF prints RET-20260811-02 in its lot field. The site's COA record explains that this identifier belongs to the 15mg fill, whose report is COA7918. Per the production lot register cited in that record, the 30mg fill is RET-20260811-01, which is also the lot on the vial labels. The record is published under the vial-label lot so a scanned vial resolves to its report. This resolves the lot mapping in the site's records; it does not change the lot number still printed on the original certificate. The record says a corrected certificate has been requested from the laboratory.

The printed PDF lot was inspected in the original source check. The repository COA comment and notice supply the production-register and vial-label explanation; the register and physical vials were not independently examined here. No corrected certificate or issuer response was obtained in this review.
Record the limit of the check
Record both exact lot identifiers, the report code, the document revision being compared, and the explanation that resolves the mapping. Here, the site's COA record supplies that explanation while preserving the original certificate's printed mismatch. A verification code on the page remains a starting point for a separate issuer check, not evidence that the check already happened. This review examined documents and repository records, not physical containers or custody history. The linked COA guide provides the broader context for sample and batch review.
