528560-94-3 Usage
Description
Telmisartan ethyl ester is an organic compound that serves as an impurity in the synthesis of Telmisartan (T017000), which is an angiotensin II receptor antagonist. It is characterized by its chemical structure and properties that differentiate it from the main compound, Telmisartan.
Uses
Used in Pharmaceutical Industry:
Telmisartan ethyl ester is used as an impurity in the synthesis of Telmisartan, an angiotensin II receptor antagonist, for the treatment of hypertension and cardiovascular diseases. The presence of this impurity is crucial for the development and production of Telmisartan, as it contributes to the overall synthesis process and the final product's efficacy.
Check Digit Verification of cas no
The CAS Registry Mumber 528560-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,5,6 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 528560-94:
(8*5)+(7*2)+(6*8)+(5*5)+(4*6)+(3*0)+(2*9)+(1*4)=173
173 % 10 = 3
So 528560-94-3 is a valid CAS Registry Number.
