Check Digit Verification of cas no

The CAS Registry Mumber 173598-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,9 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173598-96:
(8*1)+(7*7)+(6*3)+(5*5)+(4*9)+(3*8)+(2*9)+(1*6)=184
184 % 10 = 4
So 173598-96-4 is a valid CAS Registry Number.

Design of Unusual Captodative Methylene Substrates: 1-Alkyl-4(3)-(azolylmethyl)pyridinium Salts

Alcalde, Ermitas,Gisbert, Maria,Perez-Garcia, Lluisa

, p. 13365 - 13378 (2007/10/02)

The unprecedented spontaneous oxidation of a carbon atom linked to captor (acceptor) and donor non-classical functional groups of several examples of 1-alkyl-4(3)-(1H-azolylmethyl)pyridinium salts 1 and 2 exemplifies a concomitant application of the areno-analogy principle and the captodative effect in organic synthesis.A remarkably driving force by the nature of non-classical acceptor and donor heteroaromatic rings is observed upon the chemical behavior of the title compounds 1 and 2, modulating the susceptibility with which the methylene spacers oxidize to their oxomethyl counterparts 5 and 6.Access to dipolar 1-alkyl-3-pyridiniomethyl-3(5)-1,2,4-triazolate inner salts 4 was achieved.
