Check Digit Verification of cas no
The CAS Registry Mumber 87567-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,6 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87567-91:
(7*8)+(6*7)+(5*5)+(4*6)+(3*7)+(2*9)+(1*1)=187
187 % 10 = 7
So 87567-91-7 is a valid CAS Registry Number.

Quassinoid Synthesis via o-Quinone Diels-Alder Reactions
Weller, Dwight D.,Stirchak, Eugene P.
, p. 4873 - 4879 (2007/10/02)
The reaction of 3,5-disubstituted o-quinones (2a, 2c) and 4-chloro-3,5-disubstituted o-quinones (2b, 2d) with simple dienes was investigated as a potential route to the quassinoid skeleton.Quinones 2a and 2c reacted in high yield at the 3,4-position with only a small excess of diene.Attempted equilibration of cis-fused cycloadducts to the trans-fused system failed due to the intervention of a stable enol form, as in 20.Compound 2c with ethyl 3,5-hexadienoate gave 15a, which upon reduction and lactonization provided BCD-ring tricyclic quassinoid analogues 18a and 19a.Again isomerization to the BC trans-fused system was not possible.The chloroquinones showed some preference for Diels-Alder reaction at the 5,6-position, but the additions were characterized generelly by low yields, side reactions, and lessened stereoselectivity.
