6541-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6541-41-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6541-41:
(6*6)+(5*5)+(4*4)+(3*1)+(2*4)+(1*1)=89
89 % 10 = 9
So 6541-41-9 is a valid CAS Registry Number.

Uptake and metabolism of β-apo-8′-carotenal, β-apo-10′-carotenal, and β-apo-13-carotenone in Caco-2 cells

Durojaye, Boluwatiwi O.,Riedl, Kenneth M.,Curley, Robert W.,Harrison, Earl H.

, p. 1121 - 1135 (2019)

β-Apocarotenoids are eccentric cleavage products of carotenoids formed by chemical and enzymatic oxidations. They occur in foods containing carotenoids and thus might be directly absorbed from the diet. However, there is limited information about their in

Synthesis of carotenoid-monosaccharide conjugates via azide–alkyne click-reaction

Agócs, Attila,Bokor, éva,Takátsy, Anikó,Lóránd, Tamás,Deli, József,Somsák, László,Nagy, Veronika

, p. 519 - 526 (2017/01/13)

Carotenoid pentynoates were coupled to protected and unprotected sugar azides via an azide-alkyne click-reaction using bis-triphenylphosphano-copper(I)-butyrate (C3H7COOCu(PPh3)2) complex. Protected sugars delivered the conjugates with excellent yields, whereas with unprotected ones amphipathic carotenoid-sugar derivatives were obtained in good or moderate yields in a simple way.
