Most foods which are high in fiber are also very good for you for other reasons. Take, for example, fruit and vegetables and whole grains, they are high in fiber but also rich in vitamins and other essential nutrients.
Raymond Lin's MD5 & SHA-1 Checksum Utility is a standalone freeware tool that generates and verifies cryptographic hashes in MD5 and SHA-1. The program has a basic, utterly functional interface that should pose no trouble for anyone with the knowledge and skill to actually need it.
The weight for a specific position in the EAN code is either 3 or 1, which alternate so that the final data digit has a weight of 3 (and thus the check digit has a weight of 1); the same algorithm is used in other GTINs and the Serial Shipping Container Code (SSCC). The Check digit, a single checksum digit. 2  The check digit is computed modulo 10, where the weights in the checksum calculation alternate 3 and 1. 3  In particular, since the weights are relatively prime to 10 the EAN system will detect all single digit errors.
