112616-81-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 112616-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,1 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112616-81:
(8*1)+(7*1)+(6*2)+(5*6)+(4*1)+(3*6)+(2*8)+(1*1)=96
96 % 10 = 6
So 112616-81-6 is a valid CAS Registry Number.

Lithium perchlorate accelerated Friedel-Crafts addition of furans to β-nitrostyrenes

Stoermer, Martin J.,Richter, Hans-Matthias,Kaufmann, Dieter E.

, p. 6776 - 6778 (2013)

The Friedel-Crafts alkylation of furans by the Michael acceptor, β-nitrostyrene, is greatly accelerated by the use of the Lewis acid catalyst and solvent, 5 M lithium perchlorate in diethyl ether (LDPE).

Palladium(II)-catalyzed Michael-type hydroarylation of nitroalkenes using aryltins and sodium tetraarylborates

Ohe, Toshiyuki,Uemura, Sakae

, p. 1423 - 1431 (2007/10/03)

A variety of aryltin compounds and sodium tetraarylborates can be employed for Michael-type hydroarylation reactions of nitroalkenes to afford β-arylnitroalkanes in moderate to good yields in the presence of either LiCl, MgCl2, or CaCl2 and a catalytic amount of palladium(II) salt (0.05 molar amount) in acetic acid. Results show that 50-70% of aryl groups out of all in these aryl compounds can be transferred to the products in this hydroarylation. The addition of a catalytic amount (0.05-0.10 molar amount) of a Lewis acid chloride, BiCl3 or SbCl3, much improves the product yield in some cases.
