The TCGA barcode component format is {project name}-{tissue source site}-{study participant number}-{sample}-{sample vial/aliquot}-{portion of sample and analyte}-{sample plate}-{center}

Sometimes the disease name abbreviation is used to also identify the center from which the sample was derived.

Your example: TCGA-AC-A7VB-01A-11D-A350-01 TCGA project Breast Invasive Carcinoma - International Genomics Consortium Patient ID A7VB Solid Primary tumor, vial or aliquot A 11 DNA Plate ID A350 Broad Institute

The GDC has a fragmented description for each of the barcode components at this page:

This older TCGA link contains the barcode component breakdown

Does the barcode tells anything about the race of the patient ??

No, if you want patient clinical information you'll need to download the associated clinical metadata files.
