2067-32-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2067-32-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,6 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2067-32:
(6*2)+(5*0)+(4*6)+(3*7)+(2*3)+(1*2)=65
65 % 10 = 5
So 2067-32-5 is a valid CAS Registry Number.

Photochromism of nitrospiropyrans: Effects of structure, solvent and temperature

Goerner

, p. 416 - 423 (2001)

The thermal and photochemical ring opening and ring closure of the spiropyran/merocyanine couple of three nitro-substituted spiropyrans (6-NO2: 6, 7 and 8-NO2: 8) were studied and the results were compared with those of other 6-NO2 spirobenzopyranindolines (BIPS) (1-5). The photocolouration, which occurs in the triplet manifold throughout, and the photochemical conversion and thermal relaxation of the two observable photomerocyanines into the closed spiropyran (Sp) form (decolouration) were quantified as a function of solvent polarity and temperature. The relaxation time (τt-Sp) at 25°C ranges from 2 s for 5 in methylcyclohexane to 104 s for 7 in ethanol. This large variation in τt-Sp is due to changes in both the activation energy (Ea = 75-105 kJ mol-1, increasing with polarity) and the pre-exponential factor (A = 1012-1015 s-1). The quantum yield of colouration with 308 nm pulses is substantial in solvents of low polarity (φcol = 0.3-0.8) and decreases (c→t = 30-40 kJ mol-1. The effects of substituents and medium properties are described and the mechanism of photochromism is discussed.
