Resinogum benzoin, also known as Styrax benzoin, is a natural resin derived from the Styrax tree, primarily found in Southeast Asia. It is valued for its aromatic properties and has been used for centuries in traditional medicine, perfumery, and as a fixative in incense. The resin is characterized by its balsamic, vanilla-like scent and is known for its antiseptic and expectorant properties, making it useful in treating respiratory conditions. In the perfume industry, benzoin is used to enhance the longevity and depth of fragrances. It is also employed in the production of certain types of varnish and as a component in some types of adhesives. The resin is typically extracted through a process of cutting the bark of the tree, allowing the resin to ooze out and harden before being collected.
The CAS Registry Mumber 9000-73-1 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 3 respectively. Calculate Digit Verification of CAS Registry Number 9000-73: (6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*3)=71 71 % 10 = 1 So 9000-73-1 is a valid CAS Registry Number.
