1-Oxaspiro[2.5]octane, 2--ethyl is a cyclic organic compound characterized by a unique spiro structure, which consists of two rings sharing a common atom. In this case, the compound features a seven-membered ring (octane) fused with a five-membered ring (oxaspiro), with an oxygen atom at the spiro position. The 2-ethyl substitution indicates that an ethyl group (-CH2CH3) is attached to the second carbon atom of the oxaspiro ring. 1-Oxaspiro[2.5]octane, 2-ethyl- is primarily of interest in the field of organic chemistry, as it may exhibit unique chemical properties and reactivity due to its spirocyclic structure.

Check Digit Verification of cas no

The CAS Registry Mumber 28256-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,5 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28256-59:
(7*2)+(6*8)+(5*2)+(4*5)+(3*6)+(2*5)+(1*9)=129
129 % 10 = 9
So 28256-59-9 is a valid CAS Registry Number.
