Check Digit Verification of cas no

The CAS Registry Mumber 1434057-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,4,0,5 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1434057-21:
(9*1)+(8*4)+(7*3)+(6*4)+(5*0)+(4*5)+(3*7)+(2*2)+(1*1)=132
132 % 10 = 2

Synthesis of unsymmetrical imidazolium salts by direct quaternization of N-substituted imidazoles using arylboronic acids

Li, Shiqing,Yang, Fan,Lv, Taiyong,Lan, Jingbo,Gao, Ge,You, Jingsong

, p. 3941 - 3943 (2014/04/03)

Imidazolium salts were conveniently prepared by direct aryl quaternization using arylboronic acids. This process features the tolerance of a broad range of functional groups and excellent chemoselectivity, and is especially effective for the synthesis of unsymmetrical imidazolium salts.
