Check Digit Verification of cas no

The CAS Registry Mumber 21303-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,0 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21303-69:
(7*2)+(6*1)+(5*3)+(4*0)+(3*3)+(2*6)+(1*9)=65
65 % 10 = 5
So 21303-69-5 is a valid CAS Registry Number.

The cytotoxic effects of diketopiperaizes against Leishmania donovani promastigotes and amastigotes

Maity, Arindam,Hazra, Abhijit,Palit, Partha,Mondal, Shymal,Lala, Sanchaita,Mondal, Nirup B.

, p. 3452 - 3458 (2013/07/19)

A series of diketopiperazine derivatives (1-12) were evaluated for their in vitro cytotoxic activity against Leishmania donovani promastigotes and amastigotes. Cytotoxicity study revealed that the number and types of the substituents in the phenyl rings h

Efficient synthesis of piperazinediones using potassium iodide catalysis in aqueous media

Wen, Yong-Hong,Chen, Xiao-Na,Wen, Hui-Ling,Tang, Xiao-Fang

experimental part, p. 732 - 736 (2012/06/01)

A simple and efficient synthetic approach to 1,4-disubstituted piperazine-2,5-diones was developed. A series of symmetrical 1,4-disubstituted piperazine-2,5-diones was prepared from chloroacetamides using potassium iodide catalysis in acetone/water. The structures of two products were confirmed by single crystal X-ray diffraction analysis.

Synthesis of 1,4-diaryl-piperazine-2,5-diones: New behavior of N,N-dimethylformamide dimethyl acetal (DMFDMA)

Abu-Shanab, Fathi A.,Al-Harrasi, Ahmed,Mousa, Sayed A. S.

, p. 376 - 382 (2008/04/01)

Reactions of chloroacetamides (5) with N,N-dimethylformamide dimethyl acetal gave 1,4-diaryl-piperazine-2,5-diones 11a-e in good yield, rather than 1,5-diaryl-3,7-dimethoxy-1H,5H-[1,5]diazocine-2,6-diones (9a-e). Copyright Taylor & Francis Group, LLC.

Synthesis of symmetrically 1,4-disubstituted piperazine-2,5-diones: A new class of antileishmanial agents

Hazra, Abhijit,Paira, Priyankar,Palit, Partha,Banerjee, Sukdeb,Mondal, Nirup B.,Sahu, Niranjan P.

, p. 381 - 383 (2008/02/11)

A series of 1,4-diphenyl-2,5-dioxopiperazine derivatives were synthesised in one pot sequence. The compounds demonstrated appreciable cytotoxic activity against Leishmania donovani on both forms of the parasite, and the results suggested that some derivat

Synthesis of Novel Imidazole-Containing DNA Minor Groove Binding Oligopeptides Related to the Antiviral Antibiotic Netropsin

Krowicki, Krzysztof,Lown, J. William

, p. 3493 - 3501 (2007/10/02)

Analysis of the structural and stereochemical requirements for the strict DNA base sequence recognition of (AT)4 and (AT)5 respectively for the oligopeptide minor groove binding agents netropsin and distamycin leads to proposals for the rational structure
