Gramicidin is a naturally occurring antibiotic derived from the bacterium Bacillus brevis. It is a cyclic peptide composed of 15 amino acids, which forms a pore in the cell membrane of gram-positive bacteria, leading to cell death by disrupting the membrane's integrity and causing leakage of essential cellular components. Gramicidin is known for its broad-spectrum activity against various gram-positive bacteria, including Staphylococcus aureus and Streptococcus pyogenes. It is used topically to treat skin infections and is also incorporated into some over-the-counter antibiotic ointments. Due to its potential for nephrotoxicity and ototoxicity when used systemically, it is not administered orally or parenterally. Gramicidin's mechanism of action and its use in topical formulations make it a valuable component in the treatment of certain bacterial infections.

Check Digit Verification of cas no

The CAS Registry Mumber 1393-88-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,9 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1393-88:
(6*1)+(5*3)+(4*9)+(3*3)+(2*8)+(1*8)=90
90 % 10 = 0
So 1393-88-0 is a valid CAS Registry Number.
