Phosphatases are a class of enzymes that catalyze the hydrolysis of phosphoric acid monoesters, such as phosphate esters, to remove a phosphate group from various molecules. They play a crucial role in numerous cellular processes, including signal transduction, protein activation, and DNA repair. Phosphatases are essential for maintaining the balance of phosphorylation and dephosphorylation events within cells, which are critical for regulating various biological functions. These enzymes can be classified into different types based on their substrate specificity, such as protein phosphatases, which act on proteins, and nucleotide phosphatases, which act on nucleotides. Their activity is tightly regulated, and dysregulation can lead to various diseases, including cancer and neurological disorders.
The CAS Registry Mumber 9013-05-2 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 3 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 9013-05: (6*9)+(5*0)+(4*1)+(3*3)+(2*0)+(1*5)=72 72 % 10 = 2 So 9013-05-2 is a valid CAS Registry Number.
