Check Digit Verification of cas no

The CAS Registry Mumber 1338561-06-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,6 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1338561-06:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*6)+(3*1)+(2*0)+(1*6)=160
160 % 10 = 0
So 1338561-06-0 is a valid CAS Registry Number.

Synthesis and biological evaluation of HQCAs with aryl or benzyl substituents on N-1 position as potential HIV-1 integrase inhibitors

, p. 5553 - 5558 (2011/10/19)

A series of new 5-hydroxylquinolone-3-carboxylic acids (HQCAs) with various aryl or benzyl substituents on N-1 position were synthesized and evaluated for their anti-HIV activity in C8166 cell culture. Most of the target compounds displayed activity against wide-type HIV-1 in the low micromolar range in infected C8166 cells. The most active compound 5g exhibited activity against wild-type HIV-1 and HIV-1 mutant virus A17 with an EC50 value of 3.17 and 17.88 μM, respectively. The biological results and the docking study revealed that the substitution pattern on N-1 position of the quinolone core might contribute to physicochemical properties of HQCAs and resulted in great influence on their antiviral potency.
