869112-31-2 Usage
General Description
Umeclidinium Bromide Impurity 4 is a chemical compound that is present as an impurity in Umeclidinium Bromide, a medication used for the treatment of chronic obstructive pulmonary disease (COPD). This impurity is a byproduct of the manufacturing process and is undesirable due to potential effects on the safety and efficacy of the medication. The specific chemical structure and properties of Umeclidinium Bromide Impurity 4 are not readily available, but it is important to monitor and control the levels of impurities in pharmaceutical products to ensure the quality and safety of the medications for patient use.
Check Digit Verification of cas no
The CAS Registry Mumber 869112-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,1,1 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 869112-31:
(8*8)+(7*6)+(6*9)+(5*1)+(4*1)+(3*2)+(2*3)+(1*1)=182
182 % 10 = 2
So 869112-31-2 is a valid CAS Registry Number.
