Check Digit Verification of cas no
The CAS Registry Mumber 20870-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,7 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20870-37:
(7*2)+(6*0)+(5*8)+(4*7)+(3*0)+(2*3)+(1*7)=95
95 % 10 = 5
So 20870-37-5 is a valid CAS Registry Number.

(Chemical Equation Presented) 6,9-Di(tert-butyl)-1-methyltetrazolo[1,5-a] perimidine (1) has been synthesized from naphthalene in seven steps. The EPR spectra, recorded after irradiation of 1 in a butyronitrile matrix at 77 K (λ = 351 nm) and in Ar and Xe matrixes at 4.6 K (λ ≥ 345 nm), showed a six-line, high-field signal (Δms = ± 1), centered at 3350 G in butyronitrile, along with a half-field signal (Δms = ± 2), which is characteristic for triplets. Simulation of the observed EPR spectra gave values for the zero-field splitting parameters of |D/hcl/ cm-1 = 0.0105, |E/hcl/cm-1 = 0.0014 in butyronitrile and |D/hcl/cm-1 = 0.0107, |ER/hcl/cm-1 = 0.0016 in Ar. These EPR parameters are consistent with the diradical 5,8-di(tert-butyl)-2-(N-methylimino)perimidine-1,3-diyl (32) as source of the EPR spectra. Linearity of the Curie-Weiss plot and UB3LYP and (14/14)CASPT2 calculations of the singlet-triplet energy difference (ΔEST ≈ 8-10 kcal/mol) indicate that the triplet is the ground state of 2, as predicted for such a nondisjoint diradical.
