Chemical Properties
Opopanax is an oleo-gum resin that oozes through incisions made on the bark of the tree. The exudate hardens on
exposure to air, forming resinous, tear-shaped, more-or-less regular lumps approximately the size of a nut; these are detached
from the bark and used for the manufacture of the essential oil and other derivatives. The trees are native to Somaliland. Once
opopanax resin was obtained from O. chironium Koch; today the entire production of resin is obtained from C. erythraea var.
glabrescens Eng. O. chironium crude resin was offered in the form of regular, tear-shaped lumps of a brilliant red color. They
were rather soft, shiny and easily grindable. The strong, aromatic odor was reminiscent of costus and lovage. The oleo gum-resin
exudate is the part used. Opopanax has a fresh, balsamic odor reminiscent of myrrh. The crude oleoresin has a reddish-brown or
sometimes yellowish-brown color and sweet, balsamic, slightly spicy odor reminiscent of myrrh. The product is also known as
bisabol or sweet myrrh.
Composition
Opopanax contains 50 to 80% of a water-soluble gum, 15 to 40% alcohol soluble resin and 5 to 9% essential oil.
Check Digit Verification of cas no
The CAS Registry Mumber 9000-78-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 9000-78:
(6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*8)=76
76 % 10 = 6
So 9000-78-6 is a valid CAS Registry Number.
