931-12-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 931-12-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 931-12:
(5*9)+(4*3)+(3*1)+(2*1)+(1*2)=64
64 % 10 = 4
So 931-12-4 is a valid CAS Registry Number.

Strong hyperconjugative interactions limit solvent and substituent influence on conformational equilibrium: The case of cis-2-halocyclohexylamines

Francisco, Camila B.,Fernandes, Cleverton S.,de Melo, Ulisses Z.,Rittner, Roberto,Gauze, Gisele F.,Basso, Ernani A.

, p. 818 - 829 (2019)

The presence of strong stereoelectronic interactions involving the substituents in cis-2-substituted cyclohexanes may lead to results different from those expected. In this work, we studied the conformational behavior of cis-2-fluoro- (F), cis-2-chloro- (

Catalytic asymmetric ring openings of Meso and terminal aziridines with halides mediated by chiral 1,2,3-triazolium silicates

Ohmatsu, Kohsuke,Hamajima, Yuta,Ooi, Takashi

supporting information; experimental part, p. 8794 - 8797 (2012/07/02)

Catalytic asymmetric chloride and bromide ring openings of meso aziridines with trimethylsilyl halides have been developed using modular chiral 1,2,3-triazolium chlorides as catalysts. Control experiments suggest the reaction pathway involving hypervalent
