Check Digit Verification of cas no

The CAS Registry Mumber 1206198-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,1,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1206198-53:
(9*1)+(8*2)+(7*0)+(6*6)+(5*1)+(4*9)+(3*8)+(2*5)+(1*3)=139
139 % 10 = 9

Synthesis andanti-mycobacterial evaluation of some pyrazine-2-carboxylic acid hydrazide derivatives

Abdel-Aziz, Mohamed,Bdel-Rahman, Hamdy M.A.

experimental part, p. 3384 - 3388 (2010/08/13)

A series of pyrazine-2-carboxylic acid hydrazide derivatives were synthesized and screened for their activity against Mycobacterium tuberculosis. The results show that pyrazine-2-carboxylic acid hydrazi-deehydrazone derivatives 3ael were less active than pyrazinamide. In contrast,the N 4-ethyl-N1-pyr-azinoyl-thiosemicarbazide 4 showed the highest activity against M. tuberculosis H37Rv (IC90 16.87 mg/mL). Details of the structureeactivity and structureecytotoxicity relationships are discussed.
