Check Digit Verification of cas no

The CAS Registry Mumber 309267-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,2,6 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 309267-51:
(8*3)+(7*0)+(6*9)+(5*2)+(4*6)+(3*7)+(2*5)+(1*1)=144
144 % 10 = 4
So 309267-51-4 is a valid CAS Registry Number.

Mechanochemical synthesis of ethyl 4-(3-aryl-1-phenyl-1H-pyrazol-4- yl)-6-methyl-2-oxo/thioxo-1,2,3,4-tetrahydro-pyrimidine-5- carboxylates and their antimicrobial activity

Sarasija,Ashok,Sudershan,Shivaraj

, p. 349 - 352 (2019/01/21)

An efficient and greener approach has been described for the synthesis of ethyl 4- (3-aryl-1-phenyl-1H-pyrazol-4-yl)-6-methyl-2-oxo/thioxo-1,2,3,4-tetrahydropyrimidine-5- carboxylates by multicomponent reaction of 3-aryl-1-phenyl-1H-pyrazole-4- carboxalde

Novel dihydropyrimidines as a potential new class of antitubercular agents

Trivedi, Amit R.,Bhuva, Vimal R.,Dholariya, Bipin H.,Dodiya, Dipti K.,Kataria, Vipul B.,Shah, Viresh H.

supporting information; experimental part, p. 6100 - 6102 (2010/11/18)

A small library of 30 dihydropyrimidines was synthesized and evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H 37Rv. Two compounds, ethyl 4-[3-(4-fluorophenyl)-1-phenyl-1H-pyrazol- 4-yl]-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5 carboxylate 4a and ethyl 4-[3-(4-nitrophenyl)-1-phenyl-1H-pyrazol-4-yl]-6-methyl-2-oxo-1,2,3, 4-tetrahydropyrimidine-5-carboxylate 4d were found to be the most active compounds in vitro with MIC of 0.02 μg/mL against MTB and were more potent than isoniazid.
