3-(difluoromethoxy)-4-methoxybenzoic acid is used as an impurity in the production of the antiasthmatic drug Roflumilast (R639700). Its presence, although as an impurity, is significant for the drug's efficacy and safety profile. The compound plays a role in the synthesis process or may be a byproduct of the chemical reactions involved in the production of Roflumilast, which is a phosphodiesterase-4 (PDE4) inhibitor used to treat chronic obstructive pulmonary disease (COPD) and other respiratory conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 162401-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,4,0 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 162401-65:
(8*1)+(7*6)+(6*2)+(5*4)+(4*0)+(3*1)+(2*6)+(1*5)=102
102 % 10 = 2
So 162401-65-2 is a valid CAS Registry Number.
