The CAS Registry Mumber 42953-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,5 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42953-18:
(7*4)+(6*2)+(5*9)+(4*5)+(3*3)+(2*1)+(1*8)=124
124 % 10 = 4

[3 + 2] Cycloadditions and protonation by alcohols of photochemically generated nitrile ylides from 2H-Azirines. Formation and reactivities of azaallenium cations

Albrecht, Evelyn,Mattay, Jochen,Steenken, Steen

, p. 11605 - 11610 (2007/10/03)

On photolysis of 2H-phenylazirines in acetonitrile or alcohol solution with 248 nm laser light, phenylnitrile ylides are formed by heterolytic cleavage of the C-C bond of the azirines. The absorption spectra of the ylides are characterized by two strong b
