Benzoquinonium, also known as benzalkonium chloride, is a quaternary ammonium salt widely used as a disinfectant, preservative, and surfactant in various applications. It is effective against a broad range of microorganisms, including bacteria, viruses, and fungi, and is commonly found in household and industrial cleaning products, personal care items, and medical equipment. Benzoquinonium works by disrupting the cell membrane of microorganisms, leading to cell death. However, concerns have been raised about its potential environmental impact and resistance development in some microorganisms, prompting a need for responsible use and alternative solutions in certain contexts.
The CAS Registry Mumber 7554-16-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 4 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 7554-16: (6*7)+(5*5)+(4*5)+(3*4)+(2*1)+(1*6)=107 107 % 10 = 7 So 7554-16-7 is a valid CAS Registry Number.
