Quinazoline is a heterocyclic compound with the chemical formula C8H6N2, consisting of a benzene ring fused to a pyrazine ring. It is an important building block in organic synthesis and is used in the production of various pharmaceuticals, agrochemicals, and other chemical compounds. Picrate, on the other hand, is an explosive compound with the chemical formula C6H2N3O7, formed by the reaction of picric acid with a metal ion. It is commonly used as a detonator in military applications and as a reagent in analytical chemistry. Both quinazoline and picrate are significant in their respective fields, with quinazoline being a versatile intermediate in organic synthesis and picrate serving as a powerful explosive and analytical tool.
The CAS Registry Mumber 3959-96-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 9 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3959-96: (6*3)+(5*9)+(4*5)+(3*9)+(2*9)+(1*6)=134 134 % 10 = 4 So 3959-96-4 is a valid CAS Registry Number.
