85142-34-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85142-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85142-34:
(7*8)+(6*5)+(5*1)+(4*4)+(3*2)+(2*3)+(1*4)=123
123 % 10 = 3
So 85142-34-3 is a valid CAS Registry Number.

One-pot amide synthesis from allyl or benzyl halides and amines by Pd-catalysed carbonylation

Troisi, Luigino,Granito, Catia,Rosato, Francesca,Videtta, Valeria

experimental part, p. 371 - 373 (2010/03/24)

Amides can be prepared from allyl or benzyl halides and primary or secondary amines, using Pd(0) catalyst under CO pressure, in a one-pot synthesis. The reaction proceeds through the acyl palladium halide formation which undergoes an acylic nucleophilic substitution from the amine.

Carbamoylation using the CO-containing Copper Complex derived from Lithium N-methylanilide

Wakita, Yoshiaki,Kobayashi, Toshio,Maeda, Minoru,Kojima, Masaharu

, p. 3395 - 3398 (2007/10/02)

Lithium N-methylanilide, prepared from N-methylaniline and n-butyllithium, readily absorbed CO at atmospheric pressure in the presence of cuprous iodide to produce a CO-containing copper complex.Treatment of this complex with organic halides gave the corresponding amides in good yields.Keywords - carbonylation; carbamoylation; carbon monoxide; cuprous iodide; lithium N-methylanilide
