25073-30-7 Usage
Uses
Used in Pharmaceutical Industry:4,5-Epoxy-13-ethyl-17-hydroxy-18,19-dinor-17α-pregn-20-yn-3-one is used as an intermediate in the synthesis of Levonorgestrel derivatives for emergency contraception. Its role in the synthesis process is crucial, as it allows for the development of effective emergency contraceptives that can help prevent unintended pregnancies.
In the synthesis of Levonorgestrel derivatives, 4,5-Epoxy-13-ethyl-17-hydroxy-18,19-dinor-17α-pregn-20-yn-3-one serves as a key building block, enabling the creation of compounds with potent contraceptive properties. These derivatives are then formulated into various emergency contraceptive products, such as pills and intrauterine devices, which are used to prevent pregnancy in cases of contraceptive failure or unprotected sexual intercourse.
Check Digit Verification of cas no
The CAS Registry Mumber 25073-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,7 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.Calculate Digit Verification of CAS Registry Number 25073-30:
(7*2)+(6*5)+(5*0)+(4*7)+(3*3)+(2*3)+(1*0)=87
87 % 10 = 7
So 25073-30-7 is a valid CAS Registry Number.
