Check Digit Verification of cas no

The CAS Registry Mumber 1241839-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,8,3 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1241839-91:
(9*1)+(8*2)+(7*4)+(6*1)+(5*8)+(4*3)+(3*9)+(2*9)+(1*1)=157
157 % 10 = 7
So 1241839-91-7 is a valid CAS Registry Number.

Page/Page column 48-49, (2010/09/17)

A chiral ionic compound comprising an alkyl substituted imidazolium or pyridinium cationic core having an alkyl ester side chain (-alkyl-C(O)O-) directly linked to the core and an associated counter anion, characterized in that the -O- atom of the ester side chain is linked to an alpha, a beta or a gamma hydroxycarboxylic acid functionality via the alpha, beta or gamma hydroxy of the acid functionality and the hydroxycarboxylic acid functionality has at least one asymmetric carbon, or characterized in that an -N= atom of the alkyl substituted imidazolium or pyridinium cationic core is substituted with an alpha, a beta or a gamma hydroxy group of a alpha, a beta or a gamma hydroxycarboxylic acid functionality and the hydroxycarboxylic acid functionality has at least one asymmetric carbon. The chiral ionic liquids (CILs) may be used as novel solvents, in particular for organic synthesis. The CILs have the potential to induce asymmetry into substrates or catalysts in a variety of organic transformations. A number of the compounds have low antimicrobial and low antifungal toxicities and are also biodegradable CILs.
