23912-50-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23912-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,1 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23912-50:
(7*2)+(6*3)+(5*9)+(4*1)+(3*2)+(2*5)+(1*0)=97
97 % 10 = 7
So 23912-50-7 is a valid CAS Registry Number.

Amino acid based chiral N-amidothioureas. Acetate anion binding induced chirality transfer

Wang, Fang,He, Wen-Bin,Wang, Jin-He,Yan, Xiao-Sheng,Zhan, Ying,Ma, Ying-Ying,Ye, Li-Cai,Yang, Rui,Cai, Fu,Li, Zhao,Jiang, Yun-Bao

, p. 11784 - 11786 (2011/12/02)

N-Amidothioureas generated from amine-dimethylated natural l-phenylalanine and its d-enantiomer bearing a chiral carbon that is by 2 atoms or 3 chemical bonds away from the anion binding site establish chiral communication upon acetate anion binding to the thiourea moiety.

STUDIES ON THE KINETICS OF RACEMIZATION OF 2,4-DISUBSTITUTED-5(4H)-OXAZOLONES

Slebioda, Marek,St-Amand, Marc A.,Chen, Francis M. F.,Benoiton, N. Leo

, p. 2540 - 2544 (2007/10/02)

The kinetics of racemization of 2,4-disubstituted-5(4H)-oxazolones obtained from N-acetyl, N-benzoyl, and N-benzyloxycarbonylglycyl-L-leucine, -valine, and -phenylalanine have been studied in several solvents alone and in the presence of tertiary amines.T
