22980-23-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22980-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,8 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22980-23:
(7*2)+(6*2)+(5*9)+(4*8)+(3*0)+(2*2)+(1*3)=110
110 % 10 = 0
So 22980-23-0 is a valid CAS Registry Number.

Ultraviolet and Polarized Infrared Spectroscopy of Matrix-Isolated Cyclobutadiene and Its Isotopomers

Arnold, Bradley R.,Michl, Josef

, p. 13348 - 13354 (1993)

The UV and polarized IR spectra of argon matrix isolated cyclobutadiene and its 1-d-, 1,2-d2-, 1,4-d2-, 1-13C-, 1,2-13C2-, and 1,4-13C2- labeled derivatives are reported.Above 250 nm, the UV spectrum contains no peaks with an extinction coefficient larger than 10 L M-1 cm-1, but a weak absorption tail extends throughout the UV region.The absorption rises abruptly below 250 nm.The IR peak positions mostly agree with previous reports where these are available.Photoalignment studies support the symmetry assignment of fundamental vibrations and prove that the two Kekule forms interconvert rapidly even at 10 K.The spectral and photochemical effe ts of the presence of an adjacent CO2 molecule in the cyclobutadiene matrix site are elucidated.Its presence causes a substantial retardation of the photofragmentation of cyclobutadiene into two acetylenes.This is attributed to accelerated vibrational energy loss from the cyclobutadiene absorber.
