333310-17-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 333310-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,1 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 333310-17:
(8*3)+(7*3)+(6*3)+(5*3)+(4*1)+(3*0)+(2*1)+(1*7)=91
91 % 10 = 1
So 333310-17-1 is a valid CAS Registry Number.

New Method for Synthesis of Multi-substituted Imidazoles

Marzouk, Adel A.,Mohamed, Shaaban K.,Aljohani, Enas T.,Abdelhamid, Antar A.

, p. 1775 - 1782 (2018/07/25)

Here, we reported two methods for the synthesis of multi-substituted imidazoles, firstly via four-component cyclocondensation reaction of benzil, aliphatic amines (allylamine or pentylamine), and aromatic aldehyde and ammonium acetate. Using an ionic liqu

An efficient and one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles catalyzed by InCl3·3H2O

Das Sharma, Saikat,Hazarika, Parasa,Konwar, Dilip

, p. 2216 - 2220 (2008/09/18)

InCl3·3H2O was found to be a mild and effective catalyst for the efficient, one-pot, three component synthesis of 2,4,5-trisubstituted imidazoles at room temperature. Moreover, the utility of this protocol was further explored conveniently for the one-pot, four component synthesis of 1,2,4,5-tetrasubstituted imidazoles in high yields.
