2-[2-(6-Bromohexyloxy)ethoxymethyl]-1,3-dichlorobenzene is an intermediate in the synthesis of Vilanterol Trifenatate-d4 (V260002). Vilanterol Trifenatate (V260000) is a long-acting β2 adrenergic receptor Agonist. It demonstrates prolonged bronchodilation in subjects with asthma and COPD.
Check Digit Verification of cas no
The CAS Registry Mumber 503070-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 503070-57:
(8*5)+(7*0)+(6*3)+(5*0)+(4*7)+(3*0)+(2*5)+(1*7)=103
103 % 10 = 3
So 503070-57-3 is a valid CAS Registry Number.
