91178-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91178-49-3 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 91178-49:
(7*9)+(6*1)+(5*1)+(4*7)+(3*8)+(2*4)+(1*9)=143
143 % 10 = 3
So 91178-49-3 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 (1984)
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
