 ** ChecksumCRC64NVME **   <a name="AmazonS3-Type-CompletedPart-ChecksumCRC64NVME"></a>
The Base64 encoded, 64-bit `CRC64NVME` checksum of the part. This checksum is present if the multipart upload request was created with the `CRC64NVME` checksum algorithm to the uploaded object). For more information, see [Checking object integrity](https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html) in the *Amazon S3 User Guide*.  
Type: String

 ** ChecksumSHA1 **   <a name="AmazonS3-Type-CompletedPart-ChecksumSHA1"></a>
The Base64 encoded, 160-bit `SHA1` checksum of the part. This checksum is present if the multipart upload request was created with the `SHA1` checksum algorithm.

 ** ETag **   <a name="AmazonS3-Type-CompletedPart-ETag"></a>
Entity tag returned when the part was uploaded.  
Type: String  
Required: No

 ** PartNumber **   <a name="AmazonS3-Type-CompletedPart-PartNumber"></a>
Part number that identifies the part. This is a positive integer between 1 and 10,000.  
+  **General purpose buckets** - In `CompleteMultipartUpload`, when a additional checksum (including `x-amz-checksum-crc32`, `x-amz-checksum-crc32c`, `x-amz-checksum-sha1`, or `x-amz-checksum-sha256`) is applied to each part, the `PartNumber` must start at 1 and the part numbers must be consecutive. Otherwise, Amazon S3 generates an HTTP `400 Bad Request` status code and an `InvalidPartOrder` error code.
+  **Directory buckets** - In `CompleteMultipartUpload`, the `PartNumber` must start at 1 and the part numbers must be consecutive.
Type: Integer
