All-trans-5,6-dihydro-β-carotene is a naturally occurring carotenoid, which is a type of organic compound that is responsible for the yellow, orange, and red colors in many fruits and vegetables. It is a derivative of β-carotene, with the key difference being the presence of two hydrogen atoms in the 5,6 double bond, which reduces the molecule's conjugation and alters its properties. all-trans-5,6-dihydro-β-carotene is known for its antioxidant properties and is involved in the biosynthesis of vitamin A. It is also used in the food and pharmaceutical industries as a colorant and a dietary supplement. The all-trans configuration refers to the geometric arrangement of the molecule's double bonds, which is significant for its stability and biological activity.
The CAS Registry Mumber 2790-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,9 and 0 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2790-54: (6*2)+(5*7)+(4*9)+(3*0)+(2*5)+(1*4)=97 97 % 10 = 7 So 2790-54-7 is a valid CAS Registry Number.
