4412-59-3 Usage
Uses
(17α)-13-Ethyl-17-hydroxy-18,19-dinorpregna-5(10),9(11)-dien-20-yn-3-one is an intermediate in the synthesis of Gestrinone (G368800),which is a Steroidal antiestrogen, antiprogestogen, analog of Norgestrienone. Antigonadotropin.Check Digit Verification of cas no
The CAS Registry Mumber 4412-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,1 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.Calculate Digit Verification of CAS Registry Number 4412-59:
(6*4)+(5*4)+(4*1)+(3*2)+(2*5)+(1*9)=73
73 % 10 = 3
So 4412-59-3 is a valid CAS Registry Number.
