Check Digit Verification of cas no
The CAS Registry Mumber 10420-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10420-91:
(7*1)+(6*0)+(5*4)+(4*2)+(3*0)+(2*9)+(1*1)=54
54 % 10 = 4
So 10420-91-4 is a valid CAS Registry Number.

Spectroscopy and photochemistry of triplet methylpentadiynylidene (Me-C≡C-C-C≡C-H)
Thomas, Phillip S.,Bowling, Nathan P.,McMahon, Robert J.
scheme or table, p. 8649 - 8659 (2009/10/23)
Triplet carbene methylpentadiynylidene, MeC5H (1), was investigated in cryogenic matrices by IR, UV/vis, and EPR spectroscopy. Broadband irradiation (λ > 497 nm) of the isomeric diazo compounds, 1-diazo-hexa-2,4-diyne (2) or 2-diazo-hexa-3,5-diyne (3), generates tripletcarbene 1. EPR spectra yield zero-field splitting parameters (/D/hc/) 0 .62 cm-1, /E/hc/ -1), which are typicalfor a triplet carbene with axial symmetry. The electronic spectrum of t riplet 1 is characterized by a weak absorption in the near-UV and visible region (350-430 nm) with vibronic progressions corresponding to excitations of the acetylenic stretching and the terminal C≡C-H bending modes. Chemical trapping of triplet 1 in an O2-doped matrix affords carbonyl oxides derived predominantly from attack at C-3. Upon irradiation at λ > 399 nm, triplet 1 undergoes photochemical 1,2-hydrogen migration to form hex-1-ene-3,5-diyne (6).
