Δ1,3,5(10),9(11)-8,14-seco-D-homo-oestratetraen-3-ol-14,17a-dion is a complex organic compound belonging to the steroid family. It is characterized by a unique structure, featuring a Δ1,3,5(10),9(11) double bond pattern and a seco-D-homo-oestra-1,3,5(10)-trien-3-ol-14,17a-dione backbone. Δ1,3,5(10),9(11)-8,14-seco-D-homo-oestratetraen-3-ol-14,17a-dion is derived from the estratriene class of steroids, with modifications at the 8,14-seco position, leading to the loss of a carbon-carbon bond between carbons 8 and 14. The 14,17a-dione functional group indicates the presence of two carbonyl groups at the 14 and 17a positions, which are crucial for its biological activity. Δ1,3,5(10),9(11)-8,14-seco-D-homo-oestratetraen-3-ol-14,17a-dion is of interest in the field of chemistry and biochemistry due to its potential applications in pharmaceuticals and as a research tool for understanding steroidal compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 4985-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4985-08:
(6*4)+(5*9)+(4*8)+(3*5)+(2*0)+(1*8)=124
124 % 10 = 4
So 4985-08-4 is a valid CAS Registry Number.
