Uses
Used in Pharmaceutical Industry:
(R)-6-Benzyloxy-8-(oxiran-2-yl)-4H-benzo[1,4]oxazin-3-one is used as a key intermediate in the synthesis of Olodaterol (O262000), a novel inhaled β2-adrenoceptor agonist. (R)-6-Benzyloxy-8-(oxiran-2-yl)-4H-benzo[1,4]oxazin-3-one is specifically utilized for its role in creating a medication with a 24-hour bronchodilatory efficacy, which is beneficial for the treatment of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).
Check Digit Verification of cas no
The CAS Registry Mumber 869478-12-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,4,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 869478-12:
(8*8)+(7*6)+(6*9)+(5*4)+(4*7)+(3*8)+(2*1)+(1*2)=236
236 % 10 = 6
So 869478-12-6 is a valid CAS Registry Number.
