145737-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145737-02-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,7,3 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145737-02:
(8*1)+(7*4)+(6*5)+(5*7)+(4*3)+(3*7)+(2*0)+(1*2)=136
136 % 10 = 6
So 145737-02-6 is a valid CAS Registry Number.

21,23-Dithia-3,13-diazaporphycenes - novel aromatic porphycene analogues incorporating thiazole

Nu?baumer, Thomas,Krieger, Claus,Neidlein, Richard

, p. 2449 - 2457 (2007/10/03)

The syntheses of the first examples of aromatic thiazole-containing porphycene analogues 3 have been accomplished by oxidation of the corresponding 3,20:10,13-diepithio-6,9:16,19-diimino-1,11-diaza[20]annulenes 9 with DDQ. Compounds 9a-c have been synthesized by McMurry coupling reaction of the diformylated 2-(1H-pyrrol-2-yl)thiazoles 8a-c, readily available by a three-step reaction sequence using 2-pyrrolethiocarboxamide (4) as starting material. The aromaticity of the 21,23-dithia-3,13-diazaporphycenes 3 is clearly established by NMR and UV/Vis spectroscopy and verified by X-ray crystal structure analysis of 3b.
