Check Digit Verification of cas no
The CAS Registry Mumber 89353-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,5 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89353-80:
(7*8)+(6*9)+(5*3)+(4*5)+(3*3)+(2*8)+(1*0)=170
170 % 10 = 0
So 89353-80-0 is a valid CAS Registry Number.

CONVERSION OF AILANTHONE INTO SHINJULACTONE C THROUGH AN IONIC CYCLOADDITION REACTION
Ishibashi, Masami,Tsuyuki, Takahiko,Takahashi, Takeyoshi
, p. 4843 - 4846 (1983)
Ailanthone was converted into shinjulactone C with a 1α,12α:5α,13α-dicyclo-9βH-picrasane skeleton.The key reaction consists of an intramolecular ionic cycloaddition between a pentadienyl cation and an olefin.
