244206-56-2 Usage
Uses
Used in Pharmaceutical Industry:
17α-acetoxy-11β-(4-N-acetyl-N-methylaminophenyl)-19-norpregna-4,9-diene-3,20-dione is used as an impurity in the development and production of Ulipristal (U700800), a selective progesterone receptor modulator. 17α-acetoxy-11β-(4-N-acetyl-N-methylaminophenyl)-19-norpregna-4,9-diene-3,20-dione plays a significant role in the pharmaceutical industry due to its association with Ulipristal, which is utilized as an emergency contraceptive.
Used in Contraceptive Applications:
As an impurity of Ulipristal, 17α-acetoxy-11β-(4-N-acetyl-N-methylaminophenyl)-19-norpregna-4,9-diene-3,20-dione contributes to the effectiveness of emergency contraception. Ulipristal works by temporarily blocking ovulation and preventing the implantation of a fertilized egg, thus serving as a crucial component in the development of emergency contraceptives.
Check Digit Verification of cas no
The CAS Registry Mumber 244206-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,0 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 244206-56:
(8*2)+(7*4)+(6*4)+(5*2)+(4*0)+(3*6)+(2*5)+(1*6)=112
112 % 10 = 2
So 244206-56-2 is a valid CAS Registry Number.
