	After separating the digits, add the digits in each group together. Multiply the sum of the even digits by 3, then add the sum of the odd digits. To calculate the check digit, take this value modulo 10, and if not 0, subtract from 10.		After separating the digits, add the digits in each group together.

			Algorithm: check digit = (10 - (((3 * evenSum) + oddSum) % 10)) % 10

			Some United Kingdom models' serial numbers will include "UH" after the device model prefix.

	Test ("Panda") units with the same prefix as retail can be distinguished by test units having 00 or 01 as the first two digits of the serial number portion. 00 was used with the New 3DS and New 3DS XL for test units; 01 was used with the New 2DS XL test unit. Preview versions of the N2DS XL given out to the press had 01; these appear to have been test units with the development titles deleted.
