DL-Phenoxymethylpenicillensaeure, also known as DL-Penicillanic acid, is a chemical compound derived from the degradation of penicillin. It is a key intermediate in the synthesis of various semi-synthetic penicillins, which are a group of antibiotics used to treat a wide range of bacterial infections. DL-Penicillanic acid is a white crystalline solid that is soluble in water and has a molecular formula of C8H11NO3S. It is produced by hydrolyzing penicillin G or V, which breaks down the beta-lactam ring and releases the acid. DL-Phenoxymethylpenicillensaeure is essential in the pharmaceutical industry for the production of semi-synthetic penicillins, such as amoxicillin and ampicillin, which have broader-spectrum activity and are more resistant to certain bacterial enzymes than natural penicillins.

Check Digit Verification of cas no

The CAS Registry Mumber 5898-01-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5898-01:
(6*5)+(5*8)+(4*9)+(3*8)+(2*0)+(1*1)=131
131 % 10 = 1
So 5898-01-1 is a valid CAS Registry Number.
