Check Digit Verification of cas no

The CAS Registry Mumber 40963-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,6 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40963-14:
(7*4)+(6*0)+(5*9)+(4*6)+(3*3)+(2*1)+(1*4)=112
112 % 10 = 2
So 40963-14-2 is a valid CAS Registry Number.

Efficient hydration of 2-amino-2,3-dimethylbutyronitrile to 2-amino-2,3-dimethylbutyramide in a biphasic system via an easily prepared whole-cell biocatalyst

Zhu, Shujing,Ma, Xiaoqiang,Su, Erzheng,Wei, Dongzhi

, p. 3992 - 3999 (2015)

From an environmental perspective, utilizing nonconventional solvents (i.e. green solvents) with low ecological footprints is a highly beneficial alternative to using conventional organic solvents to form a reaction system. The nitrile hydratase (NHase, EC 4.2.1.84) catalyzed hydration of 2-amino-2,3-dimethylbutyronitrile (ADBN) to 2-amino-2,3-dimethylbutyramide (ADBA) in various green solvent-aqueous reaction systems was investigated in this study. After systematically optimizing the reaction conditions, the HFE-7100/H2O (v/v, 10%) biphasic system was ultimately identified as a promising reaction system for reducing product inhibition, avoiding substrate hydrolysis, and facilitating product separation and solvent recovery. The average ADBA yield of an entire batch reaction was 97.3%, which is obviously higher than those obtained with previously reported chemical or enzymatic methods. This is the first attempt to apply a fluorous solvent-aqueous biphasic system to a biocatalytic process, and the results suggest that the fluorous solvent employed in the biphasic system satisfies the requirements for green chemistry.

Substituent effect on acidity of substituted 2-(4-nitrobenzoylamino)alkanamidesin methanol-dimethyl sulfoxide mixtures

Mitas, Petr,Sedlak, Milos,Kavalek, Jaromir

, p. 85 - 93 (2007/10/03)

The dissociation constants of substituted 2-(4-nitrobenzoylamino)alkanamides, N-[2-(4-nitrobenzoylamino)aikanoyl]pyrrolidines, and N-alkyl-4-nitrobenzamides have been measured spectrophotometrically in 60 and 80% v/v DMSO. The pKA values of these N-acids are discussed from the point of view of substituents at the acetamide a-carbon atom.
