The chemical compound "(1S,5R)-2-exo,3-endo-dibenzoyloxy-4-exo-tosyloxyspiro[bicyclo[3.2.0]heptane-6,2'-1,3-dithiolane]" is a complex, chiral molecule with a unique structure. It features a spiro ring system, which is a central carbon atom shared by two rings. The compound consists of a bicyclo[3.2.0]heptane ring fused to a 1,3-dithiolane ring, with the 6-position of the bicyclo[3.2.0]heptane ring connected to the 2'-position of the 1,3-dithiolane ring through the spiro carbon. The molecule has two benzoyloxy groups at the 2-exo and 3-endo positions, respectively, and a tosyloxy group at the 4-exo position. The stereochemistry is defined by the (1S,5R) configuration, indicating the specific arrangement of atoms in three-dimensional space. (1S,5R)-2-exo,3-endo-dibenzoyloxy-4-exo-tosyloxyspiroheptane-6,2'-<1,3>-dithiolane> is significant in organic chemistry due to its intricate structure and potential applications in the synthesis of complex molecules and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 88203-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,0 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 88203-92:
(7*8)+(6*8)+(5*2)+(4*0)+(3*3)+(2*9)+(1*2)=143
143 % 10 = 3
So 88203-92-3 is a valid CAS Registry Number.
