31408-56-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31408-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31408-56:
(7*3)+(6*1)+(5*4)+(4*0)+(3*8)+(2*5)+(1*6)=87
87 % 10 = 7
So 31408-56-7 is a valid CAS Registry Number.

Biological synthesis of pharmaceuticals and biochemicals offers an environmentally friendly alternative to conventional chemical synthesis. These alternative methods require the design of metabolic pathways and the identification of enzymes exhibiting ade

Traceless synthesis of 3H-quinazolin-4-ones via a combination of solid-phase and solution methodologies

O'Mahony, Donogh J.R.,Krchňák, Viktor

, p. 939 - 942 (2007/10/03)

A solid-phase traceless synthesis of quinazolin-4-ones is described. An aldehyde functionalized resin was reductively aminated with primary amines, and the resin-bound secondary amine acylated with o-nitro-benzoic acids. The nitro group was reduced with tin(II) chloride, and the aniline acylated with acid anhydrides. Acidolytic cleavage afforded a diamide, which was cyclized in solution phase to the 3H-quinazolin-4-one removing the trace of the linker.
