Check Digit Verification of cas no

The CAS Registry Mumber 65325-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,3,2 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65325-64:
(7*6)+(6*5)+(5*3)+(4*2)+(3*5)+(2*6)+(1*4)=126
126 % 10 = 6
So 65325-64-6 is a valid CAS Registry Number.

Optimized Monofluoromethylsulfonium Reagents for Fluoromethylene-Transfer Chemistry

Sperga, Arturs,Melngaile, Renate,Kazia, Armands,Belyakov, Sergey,Veliks, Janis

, p. 3196 - 3212 (2021/02/27)

An investigation of the properties and reactivity of fluoromethylsulfonium salts resulted in the redesign of the reagents for fluoromethylene transfer chemistry. The model reaction, fluorocyclopropanation of nitrostyrene, turned out to be a suitable platf

SUBSTITUTED 5-AMINOTHIENO[2,3-C]PYRIDAZINE-6-CARBOXAMIDE ANALOGS AS POSITIVE ALLOSTERIC MODULATORS OF THE MUSCARINIC ACETYLCHOLINE RECEPTOR M4

Paragraph 001118; 001119, (2013/09/12)

In one aspect, the invention relates to substituted 5-aminothieno[2,3-c]pyridazine-6- carboxamide analogs, derivatives thereof, and related compounds, which are useful as positive allosteric modulators of the muscarinic acetylcholine receptor M4 (mAChR M4); synthesis methods for making the compounds; pharmaceutical compositions comprising the compounds; and methods of treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction using the compounds and compositions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

"Syn-effect" in the isomerization of (E)-α-fluorovinylic sulfones to the corresponding allylic sulfones under basic conditions

Nakamura, Tetsuya,Guha, Samar Kumar,Ohta, Yoshihiro,Abe, Daisuke,Ukaji, Yutaka,Inomata, Katsuhiko

, p. 2031 - 2041 (2007/10/03)

Toward the elucidation of the origin of the "syn-effect," the stereochemistry of the isomerization of (E)-α-fluorovinylic sulfones to the corresponding allylic sulfones under mild basic conditions was investigated. The ratio of (Z)-isomers of the resulting allylic sulfones decreased in the following order for the γ-substituents of the starting vinylic sulfones: F- > EtO- > CH3- > BnS- > CH3CH2- > (CH3)2CH- > (CH3)3C-, C6H5-. The fluorine atom showed the highest "syn-effect," which is herein defined as an effect that stabilizes the syn-conformation in the transition state against a steric or nonbonded repulsion; the rest of the series was in accord with previous results found in the conversion of a-unsubstituted (E)-vinylic sulfones to the corresponding allylic sulfones under similar conditions. These results were rationalized based on the σ→π* interaction.
