27979-57-3 Usage
Uses
Used in Pharmaceutical Industry:
4-Methyl-5,7-dihydroxyisobenzofuran-1(3H)-one is used as a potential impurity in the production of Mycophenolate Mofetil (MMF), which is an immunosuppressant drug. Mycophenolate Mofetil is commonly used to prevent organ rejection in patients who have undergone organ transplantation, such as kidney, heart, or liver transplants. The presence of 4-Methyl-5,7-dihydroxyisobenzofuran-1(3H)-one as an impurity in the manufacturing process of MMF is crucial to ensure the safety and efficacy of the drug.
Check Digit Verification of cas no
The CAS Registry Mumber 27979-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,7 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 27979-57:
(7*2)+(6*7)+(5*9)+(4*7)+(3*9)+(2*5)+(1*7)=173
173 % 10 = 3
So 27979-57-3 is a valid CAS Registry Number.
