Check Digit Verification of cas no

The CAS Registry Mumber 89713-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,1 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89713-29:
(7*8)+(6*9)+(5*7)+(4*1)+(3*3)+(2*2)+(1*9)=171
171 % 10 = 1
So 89713-29-1 is a valid CAS Registry Number.

Synthesis and antibacterial activity of pyridyl thioureas and arylthiosemicarbazones

Kumar,Singh,Pandeya

, p. 238 - 242 (2007/10/03)

[N-(2-pyridyl)-N'-(4-(un) substituted] thioureas and (substitutedaryl)thiosemicarbazones were synthesised and evaluated for their antibacterial activity. All aryl thiosemicarbazones showed good activity against Aeromonas hydrophilia and Salmonella typhimuriurn. But none of the pyridyl thioureas showed any prominent activity against tested bacteria.

On the synthesis of fused thiazolo[5,4-d]isoxazoles and a novel rearrangement involving conversion of 5(4H)-isoxazolones to 4(5H)-isoxazolones

Chande,Joshi

, p. 403 - 409 (2007/10/03)

The interaction of 4-bromo-3-substituted-(4H)-isoxazol-5-ones (1) with alkyl/aryl thiocarbamides (2), 4-alkyl/aryl thiosemicarbazides (7) and 2, 4-disubstituted thiosemicarbazides (12) afford 5-alkyl/ arylamino-3-substituted-thiazolo [5, 4-d]isoxazoles (3) and 6-amino/anilino-5-alkyl/arylimino-3-substituted-thiazolo[5, 4-d]isoxazoles respectively. An alternate unambiguous one step synthesis is described. The compounds have been characterised by chemical reactions and spectral data.
