Trimethylthermorubin is a synthetic chemical compound that belongs to the class of dyes known as anthraquinone dyes. It is characterized by its bright red color and is primarily used as a colorant in various applications, including textiles, plastics, and paints. The compound is synthesized by the methylation of thermorubin, which involves the addition of three methyl groups to the thermorubin molecule. Trimethylthermorubin is known for its excellent lightfastness and heat resistance, making it a preferred choice in industries where color stability is crucial. It is also used in the production of pigments and as an indicator in certain chemical reactions. However, like many synthetic dyes, it is important to handle trimethylthermorubin with care due to potential environmental and health concerns associated with its use.
The CAS Registry Mumber 74636-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,3 and 6 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 74636-07: (7*7)+(6*4)+(5*6)+(4*3)+(3*6)+(2*0)+(1*7)=140 140 % 10 = 0 So 74636-07-0 is a valid CAS Registry Number.
