441718-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 441718-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,7,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 441718-04:
(8*4)+(7*4)+(6*1)+(5*7)+(4*1)+(3*8)+(2*0)+(1*4)=133
133 % 10 = 3
So 441718-04-3 is a valid CAS Registry Number.

(±)-3,3-Diethoxycarbonyl-2-p-tolylsulfinylacrylonitrile as dienophile: Relationship between the barrier for pyramidal inversion of vinyl sulfoxides and the electronic effects of the substituents at the double bond

Yuste, Francisco,Ortiz, Benjamín,Israel Pérez,Rodríguez-Hernández, Angel,Sánchez-Obregón, Rubén,Walls, Fernando,García Ruano, José L

, p. 2613 - 2620 (2002)

The dienophilic behavior of (±)-3,3-diethoxycarbonyl-2-p-tolylsulfinylacrylonitrile (6) is reported and compared with that of trialkoxycarbonyl sulfinylethylene (3). The change of a CO2R group by a CN one increases both the reactivity and the stereoselectivity of the cycloaddition. It seems that the linear structure of the CN group increases the planarity of the system reinforcing its electron-withdrawing power and therefore improving its dienophilic behavior. Otherwise, the low configurational stability at room temperature of the sulfoxide 6, which is obtained as a racemic from its optically pure precursor, must also be a consequence of this strong electronic demand of the substituents which results in an unusually small energetic barrier for pyramidal inversion of the sulfinyl sulfur in compound 6 (ΔG?=16.3kcalmol-1 at Tc=25°C, determined by dynamic NMR spectroscopy). This is the first evidence of the existing relationship between racemization barrier of vinyl sulfoxides and the electron-withdrawing power of the groups joined to the double bond.
