Check Digit Verification of cas no

The CAS Registry Mumber 1239579-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,5,7 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1239579-87:
(9*1)+(8*2)+(7*3)+(6*9)+(5*5)+(4*7)+(3*9)+(2*8)+(1*7)=203
203 % 10 = 3
So 1239579-87-3 is a valid CAS Registry Number.

Synthesis and biological activity of 2-hydroxynicotinoyl-serine-butyl esters related to antibiotic UK-3A

Arsianti, Ade,Hanafi, Muhammad,Saepudin, Endang,Morimoto, Tsumoru,Kakiuchi, Kiyomi

, p. 4018 - 4020 (2010)

Novel 2-hydroxynicotinoyl-serine-butyl esters have been synthesized. Three-step reactions from l-serine by esterification with n-butanol, amidation with 2-hydroxynicotinic acid and esterification with the corresponding carboxylic acids gave AD-1, AD-2 and AD-3. The toxicity level of esters were determined by Brine shrimp assay, and antibiotic activity was tested against Escherichia coli, Bacillus subtilis, Staphylococcus aureus and Candida albicans. AD-3 showed greater activity as a growth inhibitor of B. subtilis and S. aureus compared to Antimycin A3.
