Check Digit Verification of cas no

The CAS Registry Mumber 333432-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,4,3 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 333432-28:
(8*3)+(7*3)+(6*3)+(5*4)+(4*3)+(3*2)+(2*2)+(1*8)=113
113 % 10 = 3
So 333432-28-3 is a valid CAS Registry Number.

Fluorene-based boronic acids as fluorescent chemosensor for monosaccharides at physiological pH

Hosseinzadeh, Rahman,Mohadjerani, Maryam,Pooryousef, Mona

, p. 549 - 555 (2015/12/04)

Two fluorene-based boronic acids, 9,9-dimethyl-9H-fluoren-2-yl-2-boronic acid (1) and 9,9-dimethyl-9H-fluoren-2,7-diyl-2,7-diboronic acid (2), were synthesized and their sensing abilities for detection of D-monosaccharides were investigated by fluorescence at physiological pH. It was found that both boronic acids 1 and 2 have high selectivity and sensitivity for D-fructose with stability constant of 47.2 and 412.9, respectively. The sensor 2 showed a linear response toward D-fructose in the concentration range from 5 × 10-5 to 10-1 mol L-1 with the detection limit of 2 × 10-5 mol L-1.

Synthesis and characterization of highly stable and efficient star-molecules

Huang, Hai-Fang,Xu, Shi-Hua,He, Yan-Bo,Zhu, Cai-Cai,Fan, He-Liang,Zhou, Xue-Hua,Gao, Xi-Cun,Dai, Yan-Feng

, p. 705 - 713 (2013/03/13)

A series of well-defined star-shaped molecules have been synthesized by Pd-catalyzed Suzuki cross-coupling starting from very simple reactants with 1,3,5-trisubstituted benzene, 2,4,6-trisubstituted pyridine and trisubstituted phenylcarbazole as the backbones. These star-molecules are all soluble in common organic solvents and electrochemically stable with reversible cyclic voltammographs and high lying HOMOs. They exhibit excellent blue-fluorescence with quantum yield up to 0.87 and high glass transition temperatures. These molecules offer potential as pure blue-light emitting, hole-transport or host materials for optoelectronic applications.

Synthesis and biological activity of new 4-(Pyridin-4-yl)-(3-methoxy-5- methylphenyl)- 1H-pyrazoles derivatives as ROS Receptor tyrosine kinase inhibitors

Park, Byung Sun,El-deeb, Ibrahim M.,Yoo, Kyung Ho,Han, Dong Keun,Tae, Jin Sung,Lee, So Ha

, p. 3629 - 3634 (2013/01/16)

A series of new 4-(pyridin-4-yl)-(3-methoxy-5-methylphenyl)-1H-pyrazoles (6a-k & 7a-l) has been rationally designed based on the structure of the lead compound KIST301080, a selective ROS receptor tyrosine kinase inhibitor, in order to study the activity of ROS of this new class of inhibitors. The compounds were synthesized and screened against ROS kinase, where compound 6h showed moderate inhibitory activity with an IC50 value of 6.25 μM. The study emphasized the importance of the acetonitrile group at the pyrazole ring and also the importance of having a hydrogen bond donor on the distal phenyl ring linked to the pyridine moiety.
