Check Digit Verification of cas no

The CAS Registry Mumber 225668-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,6,6 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 225668-35:
(8*2)+(7*2)+(6*5)+(5*6)+(4*6)+(3*8)+(2*3)+(1*5)=149
149 % 10 = 9
So 225668-35-9 is a valid CAS Registry Number.

Synthesis, antileukemic and antiplatelet activities of 2,3-diaryl-6,7-dihydro-5H-1,4-diazepines

Ramajayam,Giridhar, Rajani,Yadav,Balaraman,Djaballah, Hakim,Shum, David,Radu, Constantin

, p. 2004 - 2010 (2008)

The synthesis, antileukemic and antiplatelet activity evaluation of 2,3-diaryl-6,7-dihydro-5H-1,4-diazepines are described. In general, it was found that compound 17o showed moderate antileukemic activity against MOLT3 human leukemic cancer cell lines. An arachidonic acid induced platelet aggregation effect on washed rat platelets was studied. Compound 17i was found to be the most potent. The antiplatelet properties may be mediated by interference with the arachidonic acid pathway.

Syntheses of 4,5-diaryl-1,2,3-thiadiazoles

Karimi, Lila,Navidpour, Latifeh,Amini, Mohsen,Shafiee, Abbas

, p. 1593 - 1600 (2007/10/03)

Reaction of thionyl chloride with semicarbazones of 1-(4- methylsulfonylphenyl)-2-(4-substituted pheny)lethanone gave 4-(4- methylsulfonylphenyl)-5-(4-substituted) pheny-1,2,3-thiadiazoles 5. Compounds 5-phenyl-4-(substitutedphenyl)-1,2,3-thiadiazoles 14 were similarly prepared. Chlorosulfonation of the latter followed by ammonia gave the desired compounds 5-(4-aminosulfonylphenyl)-4-(substituted) phenyl-1,2,3-thiadiazoles 6. Copyright Taylor & Francis Inc.
