220094-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220094-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,9 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220094-27:
(8*2)+(7*2)+(6*0)+(5*0)+(4*9)+(3*4)+(2*2)+(1*7)=89
89 % 10 = 9
So 220094-27-9 is a valid CAS Registry Number.

Synthesis of a tetracyclic, conformationally constrained analogue of Δ8-THC
Huffman, John W.,Yu, Shu
, p. 2281 - 2288 (2007/10/03)
A tetracyclic, conformationally constrained analogue of Δ8-THC (2) has been synthesized in which a two carbon bridge exists between C2 and C2'. Two conceptually related syntheses of 2 are described, both of which employ 5,7-dimethoxy-4-oxo-1,2,
