31463-28-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31463-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,6 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31463-28:
(7*3)+(6*1)+(5*4)+(4*6)+(3*3)+(2*2)+(1*8)=92
92 % 10 = 2
So 31463-28-2 is a valid CAS Registry Number.

The synthesis and evaluation of new α-hydrogen nitroxides for 'living' free radical polymerization

Braslau, Rebecca,O'Bryan, Greg,Nilsen, Aaron,Henise, Jeff,Thongpaisanwong, Thanchanok,Murphy, Erin,Mueller, Laura,Ruehl, Jean

, p. 1496 - 1506 (2007/10/03)

Three N-alkoxyamines were synthesized for use in nitroxide-mediated radical polymerization. Upon thermolysis, they generate new acyclic α-hydrogen nitroxides: one adamantyl substituted and two diol-containing nitroxides. The initiators were tested in polymerization reactions in direct comparison with the initiator derived from the nitroxide TIPNO. Georg Thieme Verlag Stuttgart.

Synthesis of Adamantane Derivatives. 49. Substitution Reaction of 1-Adamantyl Chloride with Some Trimethylsilylated Unsaturated Compounds

Sasaki, Tadashi,Usuki, Arimitsu,Ohno, Masatomi

, p. 3559 - 3564 (2007/10/02)

Catalytic substitution reactions at the adamantane bridgehead were studied by using α,β- and β,γ-unsaturated trimethylsilanes.Treatment of 1-adamantyl (Ad) chloride (1) with allyltrimethylsilane and its heteroanalogues, X=Y-Z-SiMe3, in the presence of Lewis acid as a catalyst gave the products Ad-X-Y=Z, X=Y+(Ad)-Z-, and X=Y-Z-Ad, depending on the attack site of the adamantyl group on each X, Y, and Z atom.Treatment of 1 with (phenylethynyl)trimethylsilane also gave a substituted adamantane in good yield.The substitution reactions of 1 with aryl- and heteroaryltrimethylsilanes under similar conditions occurred at a position distinct from that of acetylation, indicating that adamantylation was not influenced by an electronic effect of the trimethylsilyl group.
