Uses
Used in Pharmaceutical Industry:
Estr-9-en-3-one, 11-[4-(dimethylamino)phenyl]-5,17-dihydroxy-17-(1-propynyl)-, cyclic 1,2-ethanediyl acetal, (5a,11b,17b)is used as an impurity in the synthesis of Mifepristone (M343975), a progesterone receptor antagonist with partial agonist activity. Mifepristone is utilized in various medical applications, such as inducing medical abortion and treating certain hormone-dependent conditions. The presence of Estr-9-en-3-one, 11-[4-(dimethylamino)phenyl]-5,17-dihydroxy-17-(1-propynyl)-, cyclic 1,2-ethanediyl acetal, (5a,11b,17b)- as an impurity in Mifepristone synthesis highlights its importance in the pharmaceutical industry for the development and production of progesterone receptor modulators.
Check Digit Verification of cas no
The CAS Registry Mumber 84371-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,7 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84371-64:
(7*8)+(6*4)+(5*3)+(4*7)+(3*1)+(2*6)+(1*4)=142
142 % 10 = 2
So 84371-64-2 is a valid CAS Registry Number.
