642096-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 642096-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,0,9 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 642096-86:
(8*6)+(7*4)+(6*2)+(5*0)+(4*9)+(3*6)+(2*8)+(1*6)=164
164 % 10 = 4
So 642096-86-4 is a valid CAS Registry Number.

1-Butylimidazole-derived ionic liquids: Synthesis, characterisation and evaluation of their antibacterial, antifungal and anticancer activities

Ranjan, Prabodh,Kitawat, Bheru Singh,Singh, Man

, p. 53634 - 53644 (2014)

A series of new 1-butylimidazole-based ionic liquids (3a-h) have been synthesised by the quaternisation reaction of 1-butylimidazole with different alkyl- and alkoxy-substituted aryl halides using a microwave solvent-free approach with ≈82-95% yield. The
