Check Digit Verification of cas no

The CAS Registry Mumber 25343-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25343-91:
(7*2)+(6*5)+(5*3)+(4*4)+(3*3)+(2*9)+(1*1)=103
103 % 10 = 3
So 25343-91-3 is a valid CAS Registry Number.

Bronsted acid ionic liquid as a solvent-conserving catalyst for organic reactions

Taheri, Amir,Pan, Xiaojuan,Liu, Changhui,Gu, Yanlong

, p. 2094 - 2098 (2014/10/15)

A sulfonyl-containing ammonium-based Bronsted acid ionic liquid was prepared and used as a liquid heterogeneous catalyst for organic reactions. The unique macroscopic phase heterogeneity of the IL in the reaction system not only ensures an excellent catalytic activity of the IL catalyst but also avoids the use of organic reaction solvents. The catalyst system is applicable for a wide range of reactions.
