Check Digit Verification of cas no

The CAS Registry Mumber 1638254-76-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,2,5 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1638254-76:
(9*1)+(8*6)+(7*3)+(6*8)+(5*2)+(4*5)+(3*4)+(2*7)+(1*6)=188
188 % 10 = 8
So 1638254-76-8 is a valid CAS Registry Number.

Synthesis and biological activity of Schiff base series of valproyl, N-valproyl glycinyl, and N-valproyl-4-aminobenzoyl hydrazide derivatives

Series of Schiff bases of valproic acid hydrazide, N-valproylglycine hydrazide and N-valproyl-4-aminobenzoyl hydrazide derivatives were synthesized and characterized by IR, NMR (1H- and 13C-NMR) and elemental analysis. The prepared compounds were evaluated in transgenic zebrafish embryos (Tg: flil-1: enhanced green fluorescent protein (EGFP)) for antiangiogenic activity and in HepG2 liver carcinoma cell line for anti cancer activity. The Schiff bases of N-valproylglycine hydrazide derivatives were most potent in term of suppressing angiogenic blood vessels formation and anticancer activity at very low concentration, followed by the Schiff bases of valproic acid hydrazide derivatives which exhibited moderate activity, while the Schiff bases of N-valproyl-4-aminobenzoyl hydrazide derivatives, ethyl 4-(2-propylpentanamido)benzoate (VABE) and N-(4-(hydrazinecarbonyl)phenyl)-2- propylpentanamide (VABH) in contrast exhibited pro-angiogenic activity and weaker anticancer activity which mean that these derivatives targeted a common signaling pathway in term of affecting the blood vessels formation.
