2211-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2211-28-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2211-28:
(6*2)+(5*2)+(4*1)+(3*1)+(2*2)+(1*8)=41
41 % 10 = 1
So 2211-28-1 is a valid CAS Registry Number.

Thermochemical investigation of the oxygenation of vitamin K

Flowers II, Robert A.,Naganathan, Sriram,Dowd, Paul,Arnett, Edward M.,Ham, Seung Wook

, p. 9409 - 9416 (2007/10/02)

Discovery of a new oxygenation reaction of naphthohydroquinone anions makes possible a determination of the heat of reaction (ΔHox) of oxygen with the potassium salt derived from deprotonation of the hydroquinone form of vitamin K. From that value (-33.52 ± 0.60 kcal/mol), the heat of deprotonation of vitamin KH2 (-30.03 ± 1.20 kcal/mol), and the heat of deprotonation of water (-6.05 ± 0.3 kcal/mol), the enthalpy change for converting vitamin KH2 to vitamin K oxide is established to be -57.5 kcal/mol, in reasonable agreement with our previous estimate of -62.4 kcal/mol for the oxygenation of the parent naphthohydroquinone. Indeed, in similar fashion the heat of oxygenation of the parent naphthohydroquinone was determined to be -58.47 kcal/mol, and this permits the assignment of a heat of formation to naphthoquinone epoxide of ΔHf° = -47.6 kcal/mol. Heats of oxygenation and deprotonation of a variety of related phenols and naphthols provide perspective on cation and substitution effects. These data provide strong support for the base strength amplification mechanism for the biological action of vitamin K proposed by two of us (P.D. and S.W.H.).
