552299-18-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 552299-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,2,9 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 552299-18:
(8*5)+(7*5)+(6*2)+(5*2)+(4*9)+(3*9)+(2*1)+(1*8)=170
170 % 10 = 0
So 552299-18-0 is a valid CAS Registry Number.

Limits of delocalization in through-conjugated dinitrenes: Aromatization or bond formation?

Serwinski, Paul R.,Lahti, Paul M.

, p. 2099 - 2102 (2007/10/03)

(Matrix presented) Dinitrenes 4 and 5 both can form quinonoidal structures by conjugative bond formation. However, ESR spectroscopy detects a thermally populated, excited-state, triplet quinonoidal structure only for 4, with a zero-field splitting of |D/hc| = 0.0822 cm-1, |E/hc| ? 0.0 cm-1. The tendency to maintain aromaticity in the additional ring of 5 favors a dinitrene structure (with one less formal π-bond) over a quinonoidal structure. The thermally populated quintet state of 5 has a zero-field splitting of |D/hc| = 0.287 cm-1, |E/hc| ≤ 0.002 c m-1.
