L-Chitarsaeure, also known as L-chitooligosaccharide, is a derivative of chitosan, a natural polysaccharide derived from chitin, which is found in the exoskeletons of crustaceans. L-Chitarsaeure is a low molecular weight compound that possesses various biological activities, such as antimicrobial, antifungal, and immunostimulatory properties. It is widely used in pharmaceuticals, agriculture, and food industries due to its biocompatibility, biodegradability, and non-toxic nature. Additionally, L-Chitarsaeure has been studied for its potential applications in wound healing, drug delivery systems, and as a natural preservative in food products.
The CAS Registry Mumber 490-94-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 0 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 490-94: (5*4)+(4*9)+(3*0)+(2*9)+(1*4)=78 78 % 10 = 8 So 490-94-8 is a valid CAS Registry Number.
