42481-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42481-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42481-25:
(7*4)+(6*2)+(5*4)+(4*8)+(3*1)+(2*2)+(1*5)=104
104 % 10 = 4
So 42481-25-4 is a valid CAS Registry Number.

Properties of Monoazopigments Containing Heterocyclic Amide Groups.

Szadowski,Malinowski,Wojciechowski

, p. 70 - 74 (2007/10/07)

In the reported experiments, two groups of monoazopigments containing phthalimide of naphthalimide radicals and their N-methyl- and N-phenylderivatives were synthetized. Melting points and resistances against organic solvents of the pigments were determined. On the ground of comparison of properties of pigments containng N-substituted and non-substituted imide groups a hypothesis has been advanced that the reason of unexpected thermal resistance and low solubility of the latter group of pigments is their self-association by hydrogen bonds. The hypothesis has been confirmed by infrared spectrum analysis.
