Uses

Used in Pharmaceutical Industry:
RofluMilast related substance is used as an impurity in the preparation of Roflumilast (R639700) for the treatment of chronic obstructive pulmonary disease (COPD). Its presence in the preparation process is crucial for the development and effectiveness of the drug, as it may contribute to the overall pharmacological profile of Roflumilast.

Check Digit Verification of cas no

The CAS Registry Mumber 475271-62-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,2,7 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 475271-62:
(8*4)+(7*7)+(6*5)+(5*2)+(4*7)+(3*1)+(2*6)+(1*2)=166
166 % 10 = 6
So 475271-62-6 is a valid CAS Registry Number.
