134-34-9 Usage
General Description
4-acetamido-5-hydroxynaphthalene-2,7-disulfonic acid is a chemical compound that belongs to the class of organic compounds known as naphthalene sulfonates. As evident from its name, the acid contains a naphthalene ring, which is a type of polyaromatic hydrocarbon comprising two fused benzene rings. Key defining aspects of its structure include two sulfonic acid groups and a hydroxyl and acetamido groups. It is typically utilized in scientific research, particularly in areas related to organic chemistry, polymer science, and material science. Data on its human health effects and environmental impacts is not widely available, indicating that it has been less frequently applied in industrial production.
Check Digit Verification of cas no
The CAS Registry Mumber 134-34-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134-34:
(5*1)+(4*3)+(3*4)+(2*3)+(1*4)=39
39 % 10 = 9
So 134-34-9 is a valid CAS Registry Number.

Environmental protection series of reactive dyestuffs and their use
-
Page/Page column 9, (2010/02/14)
An environmental protection reactive dyestuff of the following formula (I) is disclosed, wherein R1, R2, D, M are defined as in the specification. The dyestuff of the invention is distinguished by a high fixation and a very good build-up. It is distinguished also by a green environmental protection and a low salt, a low base, a high exhaustion, non-contain heavy metal and halogen atoms, and it has fiber-reactive properties and is very highly suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide containing fibers such as wool and nylon.
