1818-94-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1818-94-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1818-94:
(6*1)+(5*8)+(4*1)+(3*8)+(2*9)+(1*4)=96
96 % 10 = 6
So 1818-94-6 is a valid CAS Registry Number.

Theoretical and Spectroscopical Investigations of Indigo Dyes, XXII. - Preparations of 5,5'- and 6,6'-Dialkylated Indigo Dyes

Meier, Helmut,Luettke, Wolfgang

, p. 1303 - 1333 (2007/10/02)

The manifolded applicabilities of indigo dyes are strongly restricted by the low solubility of most of their representatives.We describe in this paper the preparation of a series of dialkylated indigos 1, thioindigos 2, dyes of the cibaviolett-type 3, and of the corresponding vinylogues 4, 5, and 6 by different synthetic methods.Some of the prepared compounds show a remarkable solubility and can be used for spectroscopic measurements even in non-polar solvents.
