Check Digit Verification of cas no

The CAS Registry Mumber 140681-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,8 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 140681-55:
(8*1)+(7*4)+(6*0)+(5*6)+(4*8)+(3*1)+(2*5)+(1*5)=116
116 % 10 = 6
So 140681-55-6 is a valid CAS Registry Number.

On the relative power of electrophilic fluorinating reagents of the N-F class

Gilicinski, Andrew G.,Pez, Guido P.,Syvret, Robert G.,Lal, Sankar

, p. 157 - 162 (1992)

Electrochemical measurements have been employed as a measure of the relative chemical reactivity of a series of N-F class electrophilic fluorinating reagents.A correlation has been found between the potential for the first one-electron reduction of the reagents and their observed reactivity in synthetic fluorination reactions.Comparative electrochemical data in acetonitrile and dimethylformamide are reported.

Reversible Thermal Dielectric Switch Triggered by Blooming-Flower Structural Phase Transition in Ionic Crystal without Metal

Zhang, Yu-Wei,Shi, Ping-Ping,Zhang, Wan-Ying,Ye, Qiong,Fu, Da-Wei

, p. 10153 - 10159 (2018)

Due to having excellent properties of sensitive switchable physical and/or chemical response, simple preparation, and environmentally friendly processing, bistable switches (electric switching between "on" and "off" bistable states) have gradually develop

N-halogeno compounds. Part 18. 1-Alkyl-4-fluoro-1,4-diazoniabicyclo [2.2.2] octane salts: User-friendly site-selective electrophilic fluorinating agents of the N-fluoroammonium class

Banks, R. Eric,Besheesh, Mohamed K.,Mohialdin-Khaffaf, Suad N.,Sharif, Iqbal

, p. 2069 - 2076 (2007/10/03)

Methods of synthesis are described for a range of 1-alkyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane salts [R-N+(CH2CH2)3N+-F (X-)2, where R = CH3, CH2Cl, C2H5, CF3CH2, C8H17 and (X-)2 = (TfO-)2, (BF4-)2, (PF6-)2, (TfO-, BF4-), (TfO-, PF6-), (TfO-, FSO3-)] by direct fluorination (with neat F2 at ≤20 mmHg or F2-N2 blends at 1 atm pressure) of monoquaternary salts of 1,4-diazabicyclo[2.2.2]octane [R-+N(CH2CH2)3N X-] or their 1:1 adducts with boron trifluoride, phosphorus pentafluoride, or sulfur trioxide in acetonitrile at ca - 35°C. The results of site-selective electrophilic fluorination of diethyl sodio(phenyl)malonate [→ PhCF(CO2Et)2], 1-morpholinocyclohexene (→ 2-fluorocyclohexanone), phenol (→ 2- and 4-FC6H4OH), 1- and 2-hydroxynaphthalene (→ 2- and 4-FC10H6OH, and 1-FC10H6OH and 1,1-difluoro-2-oxo-1,2-dihydronaphthalene, respectively), acetanilide (→ 2- and 4-FC6H4NHCOCH3), anisole (→ 2- and 4-FC6H4OCH3) and sodium benzenesulfinate (→ PhSO2F) with these N-fluoroammonium salts are presented.
