8023-99-2 Usage
Preparation
By steam-distillation of the leaves (needles) of P. sylvestris L.
Essential oil composition
Main constituents include α- and β-pinene, d- and l-limonene, aldehydes, dl-borneol, alcohols, terpene
alcohols, bornyl acetate, phenols and fatty acids.
Composition
The barks were analyzed to biomonitor the pollution by estimating the following inorganic and organic substances:
Al, As, B, Ca, Cd, Ce, Cr, Cu, Fe, Hg, Mo, NH4
+, Ni, NO3
-, PO4(3)-, Pb, Sr, SO4(2)-, Ti, V, W, Zr, Zn, benzo[a]pyrene, fluoranthene,
pyrene, α-hexachlorocyclohexane (α-HCH) and dichlorodiphenyltrichloroethane (DDT).* The German oil contains dextro-pinene,
d-sylvestrene, cadinene, and probably bornyl- or terpinyl-acetate (about 3.5%).
Toxicity evaluation
Both the acute oral LD50 value in rats and the acute dermal LD50 value in rabbits exceeded 5 g/kg (Levenstein, 1975). The acute oral LD50 for rats was determined by von Skramlik (1959) as 6.88 g/kg body weight, calculated to correspond to approximately 482g/70kg body weight in man.
Check Digit Verification of cas no
The CAS Registry Mumber 8023-99-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 8023-99:
(6*8)+(5*0)+(4*2)+(3*3)+(2*9)+(1*9)=92
92 % 10 = 2
So 8023-99-2 is a valid CAS Registry Number.
