91842-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91842-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,4 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91842-71:
(7*9)+(6*1)+(5*8)+(4*4)+(3*2)+(2*7)+(1*1)=146
146 % 10 = 6
So 91842-71-6 is a valid CAS Registry Number.

SUBSTITUENT EFFECTS ON THE GAS PHASE BASICITIES OF ACETOPHENONES
Mishima, Masaaki,Fujio, Mizue,Tsuno, Yuho
, p. 939 - 942 (2007/10/02)
The gas phase basicities of m- and p-substituted acetophenones have been determined by the ion cyclotron resonance (ICR) eqiulibrium constant method.The application of the LArSR Eq. to these substituent effects provides a ρ=12.2 and an r+=0.76 with excellent precision.
