Flavochrome is a term that can refer to a group of natural pigments derived from flavonoids, which are a class of secondary metabolites found in plants. These pigments are responsible for the yellow, orange, and red colors observed in various fruits, vegetables, and flowers. Flavochromes are not a single chemical compound but rather a collective term for a range of compounds that share similar structures and properties. They play a role in plant defense mechanisms and are also known for their potential health benefits, such as antioxidant and anti-inflammatory properties. The term "flavochrome" is not widely recognized in scientific literature, and it is more common to refer to these pigments as flavonoids or specific subclasses like anthocyanins, which are responsible for the red, blue, and purple colors in plants.
The CAS Registry Mumber 473-05-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 3 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 473-05: (5*4)+(4*7)+(3*3)+(2*0)+(1*5)=62 62 % 10 = 2 So 473-05-2 is a valid CAS Registry Number.
