Calculate Digit Verification of CAS Registry Number 1204122-42:
(9*1)+(8*2)+(7*0)+(6*4)+(5*1)+(4*2)+(3*2)+(2*4)+(1*2)=78
78 % 10 = 8
So 1204122-42-8 is a valid CAS Registry Number.

A 1,2,4-triazole motif was employed as a bioisostere for the ester commonly used in muscarinic antagonists, and subsequent integrative conjugation to a β2 agonist quinolinone furnished a new class of bifunctional MABAs for the treatment of COPD. Medicinal chemistry optimization using the principles of 'inhalation by design' furnished a clinical candidate with desirable pharmacological, pharmacokinetic and biopharmaceutical properties.
