Arylamidase is a group of enzymes that catalyze the hydrolysis of aryl amides, specifically breaking down the amide bond between an aryl group (a functional group derived from an aromatic ring) and an amine group. These enzymes play a crucial role in various biological processes, including the metabolism of certain drugs and neurotransmitters, as well as the degradation of environmental pollutants. Arylamidases are typically found in microorganisms, plants, and animals, and their activity can be influenced by factors such as pH, temperature, and the presence of inhibitors. The study of arylamidases is important for understanding their potential applications in biotechnology, medicine, and environmental remediation.
The CAS Registry Mumber 9012-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 2 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 9012-21: (6*9)+(5*0)+(4*1)+(3*2)+(2*2)+(1*1)=69 69 % 10 = 9 So 9012-21-9 is a valid CAS Registry Number.
