4932-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4932-23-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4932-23:
(6*4)+(5*9)+(4*3)+(3*2)+(2*2)+(1*3)=94
94 % 10 = 4
So 4932-23-4 is a valid CAS Registry Number.

Microwave-assisted synthesis and characterization of a new soluble metal-free and metallophthalocyanines peripherally fused to four 18-membered tetrathiadiaza macrocycles

Kantekin, Halit,Dilber, Gülsev,Nas, Asiye

experimental part, p. 1210 - 1214 (2010/06/13)

Preparation of some novel symmetrically tetrasubstituted metal-free phthalocyanine (6) and metallophthalocyanines (7-10) containing four 18-membered tetrathiadiaza macrocycles moieties on peripheral positions has been achieved by cyclotetramerization reaction of phthalonitrile derivative (5) in a multi-step reaction sequence. Metal-free phthalocyanine (6) was synthesized by microwave irradiation of 13,24-bis[(4-methylphenyl)sulfonyl]-6,7,14,15,23,24-hexahydro-13H,22H-tribenzo[b,h,n][1,4,10,13,7,16]tetrathiadiazacyclo-octadecine-18,19-dicarbonitrile (5) in 2-(dimethylamino)ethanol. The metallophthalocyanines (7-10) were prepared by the reaction of the phthalonitrile compound (5) with NiCl2, Zn(CH3COO)2, CoCl2, CuCl2 salts, respectively, by microwave irradiation in 2-(dimethylamino)ethanol for at 175 °C, 350 W. The new compounds were characterized by IR, 1H NMR, 13C NMR, UV-Vis, elemental analysis and MS spectra data.
