2-Methyl Ethynyl Estradiol is used as an impurity in the production of Ethynylestradiol (E685100) for [application reason]. As an impurity, it is crucial to monitor and control its presence in the final product to ensure safety, efficacy, and quality standards are met.

Check Digit Verification of cas no

The CAS Registry Mumber 3240-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3240-39:
(6*3)+(5*2)+(4*4)+(3*0)+(2*3)+(1*9)=59
59 % 10 = 9
So 3240-39-9 is a valid CAS Registry Number.
