122871-99-2 Usage
General Description
β,β-Carotene-4,4'-dione, 3,3'-dihydroxy-, (3S,3'S)-neoU- (9CI) is a chemical compound that belongs to the carotenoid family. It is a derivative of β-carotene, a pigment found in plants that is responsible for the orange and yellow colors in fruits and vegetables. This particular compound has two hydroxyl groups attached at the 3 and 3' positions, and it is in the (3S,3'S) configuration. It has potential antioxidant and anti-inflammatory properties, and it is also being studied for its potential role in cancer prevention and treatment. Its chemical structure and properties make it a subject of interest for research in the fields of nutrition, medicine, and cosmetics.
Check Digit Verification of cas no
The CAS Registry Mumber 122871-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122871-99:
(8*1)+(7*2)+(6*2)+(5*8)+(4*7)+(3*1)+(2*9)+(1*9)=132
132 % 10 = 2
So 122871-99-2 is a valid CAS Registry Number.

Starting from 6-oxo-isophorone (2) a new concept for a seven-step synthesis of (3RS,3'RS)-astaxanthin (1) has been developed.As a key feature of the new approach, the oxidation state of astaxanthin (1) is adjusted already at an early stage of the synthesis.Thus, manipulation on more complex intermediates later in the synthesis is reduced to a minimum.Acetonide 10 or dimer 13 represent the key intermediates of this concept (Scheme 2).The whole sequence has been run on a kg scale with an overall yield of 52percent (s.Scheme 5).
