Lanthiopeptin is a novel class of cyclic peptides characterized by the presence of lanthionine bridges, which are formed through the dehydration of serine and cysteine residues. These unique structures contribute to their stability and biological activity. Lanthiopeptins are produced by various bacteria and have been found to exhibit a range of bioactivities, including antimicrobial, anticancer, and immunomodulatory effects. They are of interest to researchers due to their potential applications in medicine and agriculture, as well as their ability to provide insights into the biosynthesis of complex natural products.
The CAS Registry Mumber 1405-39-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,0 and 5 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1405-39: (6*1)+(5*4)+(4*0)+(3*5)+(2*3)+(1*9)=56 56 % 10 = 6 So 1405-39-6 is a valid CAS Registry Number.
