Check Digit Verification of cas no

The CAS Registry Mumber 22492-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,9 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22492-17:
(7*2)+(6*2)+(5*4)+(4*9)+(3*2)+(2*1)+(1*7)=97
97 % 10 = 7
So 22492-17-7 is a valid CAS Registry Number.

Ultrasound assisted synthesis of imidazolium salts: An efficient way to ionic liquids

Zbancioc, Gheorghita,Mangalagiu, Ionel I.,Moldoveanu, Costel

, p. 376 - 384 (2015/02/19)

In this study a straightforward and efficient approach concerning synthesis of 1,3-diazole derivatives under ultrasound (US) irradiation as well as under conventional thermal heating (TH) is presented. N-alkylation under US irradiation may be considered environmentally friendly in terms of higher yields, smaller amounts of solvent used and an overall energy efficiency due to a substantial reduction of reaction times. A comparative study of ultrasound vs. conventional conditions has been performed. Overall, the use of US proved to be more efficient than TH. A possible explanation concerning the different behavior of imidazole and benzimidazole in the N1-alkylation reactions under US irradiation was proposed.
