Description
Methylprednisolone hemisuccinate is a glucocorticoid used to treat severe allergic reactions, asthma, autoimmune diseases, blood disorders, gastrointestinal disorders, and endocrine disorders, among others.
Synthesis
Add 6L of dimethyl sulfoxide and 1kg of succinic anhydride in the reaction kettle, stir and dissolve at 25°C, add 0.8L of triethylamine, and stir for 10 minutes; add 1kg of methylprednisolone again, react at 30°C for 3 hours, add 10% hydrochloric acid water Terminate the reaction, separate 40 L of water, and stir for 30 minutes; filter and wash with water to obtain the crude product; the crude product is dissolved in 30 times of methanol temperature, and activated carbon is decolorized to obtain methylprednisolone succinate; the yield is 119%, and the content is 99.3%.

Check Digit Verification of cas no
The CAS Registry Mumber 2921-57-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2921-57:
(6*2)+(5*9)+(4*2)+(3*1)+(2*5)+(1*7)=85
85 % 10 = 5
So 2921-57-5 is a valid CAS Registry Number.
