Benzoic acid, boric acid, and anhydride are distinct chemical compounds with unique properties and applications. Benzoic acid (C7H6O2) is a colorless, crystalline solid that is widely used as a food preservative and in the synthesis of various pharmaceuticals. It has a distinctive, slightly bitter taste and is derived from benzoic acid anhydride, which is formed by the oxidation of toluene. Boric acid (H3BO3), on the other hand, is a weak, monobasic acid that is commonly used as an antiseptic, insecticide, and flame retardant. It is a white, crystalline solid that is soluble in water and has a wide range of applications in various industries. Anhydride, in general, refers to a compound that has lost water, such as an acid anhydride, which is formed by the removal of a water molecule from two acid molecules. For example, benzoic anhydride (C14H10O3) is formed by the dehydration of two benzoic acid molecules, and it is used as a reagent in organic synthesis and as a plasticizer. Each of these chemicals plays a significant role in different areas of chemistry and industry, from food preservation to pharmaceuticals and beyond.
The CAS Registry Mumber 7796-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 6 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7796-33: (6*7)+(5*7)+(4*9)+(3*6)+(2*3)+(1*3)=140 140 % 10 = 0 So 7796-33-0 is a valid CAS Registry Number.
