756819-68-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 756819-68-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,1 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 756819-68:
(8*7)+(7*5)+(6*6)+(5*8)+(4*1)+(3*9)+(2*6)+(1*8)=218
218 % 10 = 8
So 756819-68-8 is a valid CAS Registry Number.

Tunable protic ionic liquids as solvent-catalysts for improved synthesis of multiply substituted 1,2,4-triazoles from oxadiazoles and organoamines

Chen, Xiaofeng,Liu, Rui,Xu, Yuan,Zou, Gang

experimental part, p. 4813 - 4819 (2012/07/31)

More than green alternatives to traditional volatile molecular organic solvents, protic ionic liquids as dual solvent-catalysts have been successfully used to promote reactions of organoamines with oxadiazoles to afford sterically hindered 1,2,4-triazoles. Among the tested protic ionic liquids, pyridinium trifluoroacetate and acetate showed the highest efficiency for the reactions of arylamines and alkylamines, respectively, indicating that tunable catalysis could be readily effected with protic ionic liquid solvent-catalysts by simply tuning their cation and anion counterparts. A general and efficient approach has been developed for synthesis of multiply substituted 1,2,4-triazoles based on the tunable protic ionic liquid solvent-catalyst systems.

Microwave-assisted and efficient one-pot synthesis of substituted 1,2,4-triazoles

Li, Daliang,Bao, Hongli,You, Tianpa

, p. 1957 - 1962 (2007/10/03)

An efficient microwave-assisted one-pot and three-component synthesis of substituted 1,2,4-triazoles has been achieved utilizing substituted primary amines.
