11,12,11',12'-Tetradehydro-β,β-carotene is a naturally occurring carotenoid, which is a class of organic compounds that are responsible for the yellow, orange, and red colors in plants and photosynthetic organisms. This specific compound is a derivative of β-carotene, a well-known precursor to vitamin A, and is characterized by the presence of four double bonds in its molecular structure. It is found in various fruits and vegetables, such as tomatoes and carrots, and plays a crucial role in the photosynthetic process by capturing light energy and transferring it to chlorophyll molecules. Additionally, 11,12,11',12'-tetradehydro-β,β-carotene has been studied for its potential health benefits, including antioxidant properties and its ability to protect cells from damage caused by free radicals.

Check Digit Verification of cas no

The CAS Registry Mumber 4517-40-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4517-40:
(6*4)+(5*5)+(4*1)+(3*7)+(2*4)+(1*0)=82
82 % 10 = 2
So 4517-40-2 is a valid CAS Registry Number.
