Check Digit Verification of cas no

The CAS Registry Mumber 56888-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,8 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56888-63:
(7*5)+(6*6)+(5*8)+(4*8)+(3*8)+(2*6)+(1*3)=182
182 % 10 = 2
So 56888-63-2 is a valid CAS Registry Number.

On the Reactivity of Penicillamine and its Derivatives. Joint Reaction of Elementary Sulfur and Gaseous Ammonia with Ketones, 97

Asinger, Friedrich,Gluzek, Karl-Heinz

, p. 47 - 63 (2007/10/02)

DL-penicillamine-hydrochloride was condensed with various aldehydes (1 - 22) and ketones (23 - 28) to the corresponding 5,5-dimethyl-thiazolidine-4-carboxylic acid hydrochlorides and the free bases respectively.Their methylesters were obtained with diazomethane or methanol (29 - 35).Various 5,5-dimethyl-thiazolidine-4-carboxylic acids were formylated in position 3 (36 - 39).The reactivity of the carboxylic group was studied for 3-formyl-2,2,5,5-tetramethyl-thiazolidine-4-carboxylic acid.Substituted N-penicillaminamides were obtained for the first time (40 - 53).Also some S-alkylated penicillamines were prepared (54 - 60).By diazotation of 2,2,5,5-tetramethyl-thiazolidine-4-carbonamide or of penicillaminamide itself, 2-carbamyl-3,3-dimethyl-ethylene-sulfide was obatined. - Keywords: 3-Formyl-2,2,5,5-tetramethyl-thiazolidine-carboxylic acid amides; N-Formyl-5,5-dimethyl-thiazolidine-4-carboxylic acids; S-Alkylpenicillamines
