Triphenyltin is used in organic synthesis for the preparation of various organic compounds, including pharmaceuticals, dyes, and polymers. Its reactivity with organic substrates allows for the formation of new chemical bonds and the synthesis of complex molecules for research purposes.
Check Digit Verification of cas no
The CAS Registry Mumber 7242-95-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7242-95:
(6*7)+(5*2)+(4*4)+(3*2)+(2*9)+(1*5)=97
97 % 10 = 7
So 7242-95-7 is a valid CAS Registry Number.

Stereochemistry of acid-catalyzed cleavage of 3-chloro- and 3-bromonortricyclene in deuterated medium. Evidence for edge protonation of nortricyclenes
Werstiuk, Nick Henry,Timmins, George,Cappelli, Frank Peter
, p. 1709 - 1724 (2007/10/02)
Cleavage of 3-chloronortricyclene (4c) and 3-bromonortricyclene (4d) occurs faster than solvolysis in D2SO4-DOAc at 70-75 deg C and yields syn-7-, anti-7-, exo-5-, and endo-5-halo-exo-2-norbornyl acetates as products.That the 7-chloroacetates comprise 70percent of the reaction mixture, that 30percent of the 5-chloro-exo-2-norbornyl acetates which comprised 28percent of the reaction mixture are derived via rearrangement of the syn-7- and anti-7-chloronorbornyl cations, and that the deuterium at C-6 is at least 90percent stereochemically pure endo is evidence that cleavage of the bond farthest removed from the electron withdrawing halogen is preferred 5:1 over the other bonds of the three-membered ring.The stereochemistry of the ring-opening is rationalized on the basis of cleavage via edge-deuteronation with formation of classical halocations as intermediates.The location of deuterium in the 5-halo-exo-norbornyl acetates is used to define the pathways whereby the 5-haloacetates are formed.This study also establishes that C-6 endo deuterated 7-chloro- and 7-bromo-exo-2-norbornyl brosylates can be synthesized from the corresponding 3-halonortricyclenes.
