Check Digit Verification of cas no

The CAS Registry Mumber 118482-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,8 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118482-08:
(8*1)+(7*1)+(6*8)+(5*4)+(4*8)+(3*2)+(2*0)+(1*8)=129
129 % 10 = 9
So 118482-08-9 is a valid CAS Registry Number.

Basicity of azoles: Vi.1 Reaction of 1-vinyl-2-formylimidazole and its cation with water and alcohols

Baikalova,Gavrilova,Chipanina,Turchaninov

, p. 436 - 441 (2007/10/03)

The UV spectra of 1-vinyl-2-formylimidazole and its cation were interpreted and their hydration was studied on the basis of quantum-chemical calculations of the UV spectra of these compounds. The cationic form is more actively hydrated. The equilibrium constants of dehydration of neutral molecules and their cations increase in the following order of substituents: 1-vinylimidazole, pyridine, and 1-vinylbenzimidazole, in accordance with an increase in the basicity of these hetrocycles. The qualitative features of addition of alcohols to 1-vinyl-2-formylimidazole were considered.

UV spectra of 1-vinylbenzimidazole-2-carbaldehyde and its cation. Hydration and addition of alcohols

Baikalova,Gavrilova,Shulunova,Chipanina,Danovich,Turchaninov

, p. 129 - 136 (2007/10/03)

Reversible addition of water to 1-vinylbenzimidazole-2-carbaldehyde and the corresponding cation was studied by UV spectroscopy. The cation turned out to be more reactive (K+l = 1.2 l/mol) than the neutral molecule (K0l = 2.9 × 10-2 l/mol). The concentration constants of acid dissociation of the hydrated and nonhydrated cations in aqueous solution were estimated at K+l 1.2 × 103 and 4.8 × 104 l/mol, respectively. Alcohols add to 1-vinylbenzimidazole-2-carbaldehyde without a catalyst, and the addition is reversible.
