91178-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91178-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91178-48:
(7*9)+(6*1)+(5*1)+(4*7)+(3*8)+(2*4)+(1*8)=142
142 % 10 = 2
So 91178-48-2 is a valid CAS Registry Number.

Spectral Properties and Basicity of Stilbazolium Betaines Containing Bulky Substituents on the Quinoid Ring
Gruda, Ilona,Bolduc, Francois
, p. 3300 - 3305 (2007/10/02)
Several derivatives of 4--1,4-dihydropyridine were synthesized.The effect of bulky substituents in the immediate vicinity of carbonyl on the basicity and visible spectra of these compouds is described.The basici
