17652-16-3 Usage
General Description
4,9(11)-PREGNADIEN-3,20-DIONE, also known as prednisolone, is a synthetic steroid that is commonly used as an anti-inflammatory and immunosuppressant medication. It belongs to the class of glucocorticoids and is derived from cortisone. Prednisolone works by reducing inflammation and suppressing the immune system, making it useful in the treatment of a variety of conditions such as allergies, asthma, autoimmune diseases, and inflammatory disorders. It is available in various forms including tablets, syrups, and injections, and is often prescribed for short-term and long-term use depending on the individual's condition. Despite its effectiveness, prednisolone can also have side effects such as increased risk of infection, weight gain, and mood changes, so it should be used with caution and under the guidance of a healthcare professional.
Check Digit Verification of cas no
The CAS Registry Mumber 17652-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17652-16:
(7*1)+(6*7)+(5*6)+(4*5)+(3*2)+(2*1)+(1*6)=113
113 % 10 = 3
So 17652-16-3 is a valid CAS Registry Number.
