144428-02-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144428-02-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,2 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144428-02:
(8*1)+(7*4)+(6*4)+(5*4)+(4*2)+(3*8)+(2*0)+(1*2)=114
114 % 10 = 4
So 144428-02-4 is a valid CAS Registry Number.

Free-Radical Homolytic Substitution at Selenium: An Efficient Method for the Preparation of Selenophenes

Lyons, Jennifer E.,Schiesser, Carl H.,Sutej, Katarina

, p. 5632 - 5638 (1993)

Substituted and unsubstituted 1-(benzylseleno)-4-iodobut-3-en-2-ols 12 and 2-(benzylseleno)-1-(2-iodophenyl)ethanols 18 react smoothly with tris(trimethylsilyl)silane in benzene at 80 deg C (AIBN initiator) to afford selenophenes 16 and benzoselenophenes 21 in excellent yield.These reactions presumably involve intramolecular homolytic substitution by aryl and vinyl radicals 14 and 20 at the selenium atom with the expulsion of benzyl radical followed by facile dehydration to afford the aromatic selenophene ring system in each case.Competitive rate studies on the ring closure of the 2-phenyl radical 25 in the presence of tri-n-butyltin hydride to give 2,3-dihydrobenzoselenophene (27) and 1-(benzylseleno)-2-phenylethane (28) provide a rate constant for ring closure (kc) of approximately 3E7 s- at 80 deg C.The determination of more accurate data is hampered by what we attribute to be the involvement of a slow, but competive nonradical process.
