(5S,6S,7E,10aR)-5,6-Diethyl-5,6,10a,11-tetrahydro-10a-methyl-1H-cyclonona[1,2-c:4,5-c']difuran-1,3,8,10(4H)-tetrone is a complex organic compound characterized by its unique molecular structure. It features a cyclononane ring system with two fused furan rings, which are five-membered aromatic rings containing oxygen. The compound has a 5,6-diethyl substitution, indicating two ethyl groups attached to the 5th and 6th carbon atoms. Additionally, it has a 10a-methyl group, which is a methyl group attached to the 10a position of the cyclononane ring. The compound's structure is further defined by its 5,6,10a,11-tetrahydro nature, suggesting the presence of four hydrogen atoms bonded to the carbon framework. The compound's name also indicates the presence of four ketone groups, which are carbonyl groups (C=O), located at the 1, 3, 8, and 10 positions. This chemical is a specific isomer, with the (5S,6S,7E,10aR) configuration, which describes the three-dimensional arrangement of the molecule's atoms.

Check Digit Verification of cas no

The CAS Registry Mumber 743-07-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 743-07:
(5*7)+(4*4)+(3*3)+(2*0)+(1*7)=67
67 % 10 = 7
So 743-07-7 is a valid CAS Registry Number.
