847749-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 847749-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,7,4 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 847749-07:
(8*8)+(7*4)+(6*7)+(5*7)+(4*4)+(3*9)+(2*0)+(1*7)=219
219 % 10 = 9
So 847749-07-9 is a valid CAS Registry Number.

Mesogens based on palladium orthometallated complexes with carboxylato bridges: Tuning and shaping a non-planar molecule

Díez, Laura,Espinet, Pablo,Miguel, Jesús A.,Rodríguez-Medina, M. Paz

, p. 261 - 268 (2007/10/03)

The binuclear cyclopalladated compounds [Pd2(μ-OH) 2(Ln)2] (1) derived from imines HLn = p-CnH2n + 1O-C6H4-CHN-C 6H4-OCnH2n + 1-p (n = 6,10) react with carboxylic acids to give the derivatives [Pd2(μ-ox) 2(Ln)2] (2) with a planar core for oxalic acid, and [Pd2(μ-OOCR)2(Ln)2] (3-7) compounds with a non-planar ridge tent structure for other RCOOH acids: (3) R = CmH2m + 1 (m = 1, 3, 5, 7, 9, 11, 13, 15, 17); (4) R = CH2(OCH2CH2)pOCH3 (p = 1, 2); (5) R = CH2-C6H4-OCqH 2q + 1-p (q = 2, 4, 6, 8, 10, 12); (6) R = C6H 4-OCrH2r + 1-p (r = 4, 10); (7) R = C*H(OH)CH3. The acids used were designed to explore the effect on the thermal properties of the compounds prepared of systematic variations in the type of carboxylato ligand, which induce structure, packing, and polarity changes, and in the length of the carboxylato chain. Most of the complexes prepared, even when far from planar, show liquid crystal behavior and display nematic, smectic A and smectic C phases.
