17,17-Ethanediyldioxy-3-methoxy-estra-2,5(10)-diene is a complex organic compound belonging to the steroid family, specifically a derivative of estradiol, a naturally occurring estrogen hormone. 17,17-ethanediyldioxy-3-methoxy-estra-2,5⁽¹⁰⁾-diene is characterized by the presence of two ethylene oxide groups (-O-CH2-CH2-O-) at the 17th carbon position, a methoxy group (-OCH3) at the 3rd carbon position, and a double bond between the 2nd and 5th carbon atoms. The compound's structure is further defined by the presence of a 10-membered ring (indicated by the ⁽¹⁰⁾), which is a common feature in steroidal compounds. This specific arrangement of functional groups and the ring system contributes to its unique chemical properties and potential biological activities.

Check Digit Verification of cas no

The CAS Registry Mumber 1238-30-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1238-30:
(6*1)+(5*2)+(4*3)+(3*8)+(2*3)+(1*0)=58
58 % 10 = 8
So 1238-30-8 is a valid CAS Registry Number.
