Check Digit Verification of cas no

The CAS Registry Mumber 67591-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,9 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67591-20:
(7*6)+(6*7)+(5*5)+(4*9)+(3*1)+(2*2)+(1*0)=152
152 % 10 = 2
So 67591-20-2 is a valid CAS Registry Number.

Synthesis and trypanocide activity of chloro-l-tyrosine and bromo-l-tyrosine derivatives

Pastrana Restrepo, Manuel,Galeano Jaramillo, Elkin,Martínez Martínez, Alejandro,Robledo Restrepo, Sara

, p. 2454 - 2465 (2018/10/02)

Twenty-two halogenated l-tyrosine derivatives were synthesized to examine new substances for the treatment of Chagas disease. The synthesis of these derivatives with different degree of substitution in the amino group with methyl iodide, giving primary, tertiary, and quaternary amino acids. All compounds were tested in vitro against intracellular amastigotes of Trypanosoma cruzi, and the cytotoxicity were evaluated over monocytic cell line U-937. Compound 25 was the most active against T. cruzi with a EC50 of 75.52 μM compared with benznidazole with a EC50 of 58.79 μM. Compounds 3, 4, 7, and 15 were the derivatives with the best selectivity index (SI) with values of 7.5, 8.3,12.1, and 8.6, respectively. Finally, compound 7 was the safer and the more promising derivative against T. cruzi.
