Check Digit Verification of cas no

The CAS Registry Mumber 1243209-98-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1243209-98:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*0)+(3*9)+(2*9)+(1*8)=134
134 % 10 = 4
So 1243209-98-4 is a valid CAS Registry Number.

Amidinium based ionic liquids

Dechambenoit, Pierre,Ferlay, Sylvie,Kyritsakas, Nathalie,Hosseini, Mir Wais

, p. 1184 - 1199 (2010/08/08)

Three new series of mono-and bis-cyclic amidinium cations bearing alkyl chains of different length were synthesized. 53 salts were generated upon combining the cations with a variety of anions and their thermal behaviour was investigated. Depending on the structure and the charges state of the cyclic amidinium moiety and the nature of the anion, several of the obtained salts behaved as ionic liquids with their melting point in the range of ca. 25-94 °C.
