Uses
17-?Ethinyl-?17-?hydroxy-?18-?methylestra-?5(10)?,?9(11)?-?dien-?3-?one-?3-?ethylene Ketal 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 23637-79-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,3 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 23637-79:
(7*2)+(6*3)+(5*6)+(4*3)+(3*7)+(2*7)+(1*9)=118
118 % 10 = 8
So 23637-79-8 is a valid CAS Registry Number.
