561064-18-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 561064-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,1,0,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 561064-18:
(8*5)+(7*6)+(6*1)+(5*0)+(4*6)+(3*4)+(2*1)+(1*8)=134
134 % 10 = 4
So 561064-18-4 is a valid CAS Registry Number.

Synthesis of substituted 6-anilinouracils and their inhibition of DNA polymerase IIIC and gram-positive bacterial growth

Zhi, Chengxin,Long, Zheng-Yu,Gambino, Joseph,Xu, Wei-Chu,Brown, Neal C.,Barnes, Marjorie,Butler, Michelle,LaMarr, William,Wright, George E.

Certain substituted 6-anilinouracils are potent and selective inhibitors of Gram+ bacterial DNA polymerase IIIC (pol IIIC). In addition, analogues with 3-substituents in the uracil ring have potent antibacterial activity against Gram+ organisms in culture. In an attempt to find optimal anilino substituents for pol IIIC binding and optimal 3-substituents for antibacterial activity, we have prepared several series of 3-substituted-6-aminouracils and assayed their activity against pol IIIC from Bacillus subtilis and a panel of Gram+ and Gram- bacteria in culture. The 6-(3-ethyl-4-methylanilino) group and closely related substituent patterns maximized pol IIIC inhibition potency. Among a series of 3-(substituted-butyl)-6-(3-ethyl-4-methylanilino)uracils, basic amino substituents increased pol IIIC inhibition, but decreased antibacterial activity. The most potent antibacterials were simple hydroxybutyl and methoxybutyl derivatives, and hydrophobically substituted piperidinylbutyl derivatives.
