21132-20-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21132-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,3 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21132-20:
(7*2)+(6*1)+(5*1)+(4*3)+(3*2)+(2*2)+(1*0)=47
47 % 10 = 7
So 21132-20-7 is a valid CAS Registry Number.

Oxovanadium(IV) Schiff base complex derived from phenylalanine analogue containing 2,3-diaminopropionic acid (DAP): Synthesis, computational study, and biological evaluation

Wei, Le,Yang, Xia,Gao, Zeng-Qiang,Wang, Dong-Qi,Xue, Jing-Quan,Yang, Wen-Jiang,Wang, Jian-Jun,Zhang, Yan-Hua,Fang, Guo-Liang,Liu, Yu

, p. 455 - 467 (2015)

Reduced Schiff base ligand by condensation of phenylalanine analogue containing 2,3-diaminopropionic acid (DAP) with salicylaldehyde and its oxovanadium(IV) complex have been prepared. Chemical and structural properties were fully characterized. Density f

Tetrazole analogs of phenylalanine derivatives as tyrosine hydroxylase inhibitors

McNeil,Williams Jr.,Darling

, p. 1642 - 1644 (2007/10/08)

Eight new tetrazole analogs of phenylalanine derivatives in which the carboxyl group was replaced by a tetrazole ring were synthesized. At a concentration of 2.5 x 10-5 M, each compound exhibited greater than 50% inhibition of tyrosine hydroxylase activity.
