Validate a CAS Registry Number's format and check digit

Validates a CAS Registry Number's format and its check digit, fully locally (no upstream call). confidence 1.0 = format and check digit valid; 0.7 = valid format but the check digit is wrong (likely a transcription error); 0.0 = not a CAS Registry Number format. Charges 1 cost_unit.

Query parameters

include_receiptboolean

Set true to attach an execution receipt at meta.receipt — caller-verifiable sha256 hashes over the RFC 8785 (JCS) canonicalization of this call's as-received JSON body and its result (free, like include_trace). Reproduce with any JCS library: input_hash = sha256(jcs({"tool": <request path>, "args": <your body minus include_trace/include_receipt>})); result_hash = sha256(jcs(result)). For deterministic tools, same input on the same build reproduces result_hash.
