Check Digit Verification of cas no
The CAS Registry Mumber 765-46-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 765-46:
(5*7)+(4*6)+(3*5)+(2*4)+(1*6)=88
88 % 10 = 8
So 765-46-8 is a valid CAS Registry Number.

The bond length between C8-C9 in (1′ R,4′ S,4a′ R,8a′ S)-6′,7′-dimethyl-1′,4′,4a′,8a′-tetrahydrospiro [cyclopropane-1,9′-[1,4]methanonaphthalene]-5′,8′-dione is 1.571 (2) ? and between C7-C12 is 1.567 (2) ? which are longer than the corresponding bond length for saturated bicyclic systems (1.531-1.535 ?). This paper reports the correlation between bond length and the ease of retro Diels -Alder reaction.
