Check Digit Verification of cas no

The CAS Registry Mumber 16297-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,9 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16297-19:
(7*1)+(6*6)+(5*2)+(4*9)+(3*7)+(2*1)+(1*9)=121
121 % 10 = 1
So 16297-19-1 is a valid CAS Registry Number.

Halogen Bonds of Halotetrafluoropyridines in Crystals and Co-crystals with Benzene and Pyridine

Schwabedissen, Jan,Trapp, Pia C.,Stammler, Hans-Georg,Neumann, Beate,Lamm, Jan-Hendrik,Vishnevskiy, Yury V.,K?rte, Leif A.,Mitzel, Norbert W.

, p. 7339 - 7350 (2019)

The structures of the three para-substituted halotetrafluoropyridines with chlorine, bromine, and iodine have been determined in the solid state (X-ray diffraction). The structures of these compounds and that of pentafluoropyridine were also determined in the gas phase (electron diffraction). Structures in the solid state of the bromine and iodine derivatives exhibit halogen bonding as a structure-determining motif. On the way to an investigation of halogen bond formation of halotetrafluoropyridines in the solid state with the stronger Lewis base pyridine, co-crystals of benzene adducts were investigated to gain an understanding of the influence of aryl–aryl interactions. These co-crystals showed halogen bonding only for the two heavier halotetrafluoropyridines. In the pyridine co-crystals halogen bonding was observed for all three para-halotetrafluoropyridines. The formation of homodimers and heterodimers with pyridine is also supported by quantum-chemical calculations of electron density topologies and natural bond orbitals.

Preparation of p-substituted tetrafluoropyridyl derivatives via the tetrafluoropyridylcopper reagent

Van Nguyen, Ba,Burton, Donald J.

, p. 144 - 154 (2012/03/27)

A new and improved preparation of 4-iodo-2,3,5,6-tetrafluoropyridine from pentafluoropyridine is described. This iodopyridine is utilized for the in situ preparation of the 4-tetrafluoropyridylcopper reagent, 1, via two methods. The first method involves metathesis of the 4-tetrafluoropyridylcadmium reagent with Cu(I)Br at room temperature. The requisite cadmium reagent was readily prepared in situ via reaction between 4-iodotetrafluoropyridine with acid-washed cadmium powder in DMF at room temperature. The second method involves the in situ reaction of 4-tetrafluoropyridyltributyl-phosphonium tetrafluoroborate with Na2CO3 and Cu(I)Br in DMF at room temperature. 1 readily undergoes reaction with allylic halides, vinyl iodides, aryl halides, acid chlorides and acetylenic iodides at room temperature to stereospecifically afford the corresponding 4-tetrafluoropyridyl derivatives. An alternative route to the alkyne derivatives was developed via the Pd(0) catalyzed reaction of 4-iodotetrafluoropyridine with 1-alkynes.
