Check Digit Verification of cas no

The CAS Registry Mumber 1321532-26-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,5,3 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1321532-26:
(9*1)+(8*3)+(7*2)+(6*1)+(5*5)+(4*3)+(3*2)+(2*2)+(1*6)=106
106 % 10 = 6
So 1321532-26-6 is a valid CAS Registry Number.

Synthesis of new compounds derived from metronidazole and amino acids and their esters as antiparasitic agents

Al-Masri, Ahmed T.,Saadeh, Haythem A.,Mosleh, Ibrahim M.,Mubarak, Mohammad S.

, p. 1700 - 1707 (2012/11/13)

A number of new compounds derived from metronidazole and amino acids and their esters have been synthesized through a reaction between 2-(2-methyl-5-nitro-1H-imidazol-1-yl)acetic acid and a number of amino acid esters in the presence of N,N'carbonyldiimidazole (CDI). Hydrolysis of the esters derivatives with sodium hydroxide (4%) followed by acidification with hydrochloric acid (3 M) afforded the corresponding acids. The newly synthesized compounds were characterized by elemental analysis and by spectroscopic techniques such as 1H-NMR, 13C-NMR, and mass spectrometry. Some of the prepared compounds exhibited lethal activity against pathogenic protozoan parasites. Springer Science+Business Media, LLC 2011.
