Check Digit Verification of cas no

The CAS Registry Mumber 79387-69-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,8 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79387-69:
(7*7)+(6*9)+(5*3)+(4*8)+(3*7)+(2*6)+(1*9)=192
192 % 10 = 2
So 79387-69-2 is a valid CAS Registry Number.

Evaluation of α-pyrones and pyrimidones as photoaffinity probes for affinity-based protein profiling

Battenberg, Oliver A.,Nodwell, Matthew B.,Sieber, Stephan A.

experimental part, p. 6075 - 6087 (2011/10/09)

α-Pyrones and pyrimidones are common structural motifs in natural products and bioactive compounds. They also display photochemistry that generates high-energy intermediates that may be capable of protein reactivity. A library of pyrones and pyrimidones was synthesized, and their potential to act as photoaffinity probes for nondirected affinity-based protein profiling in several crude cell lysates was evaluated. Further "proof-of-principle" experiments demonstrate that a pyrimidone tag on an appropriate scaffold is equally capable of proteome labeling as a benzophenone.

Development of a concise scaleable synthesis of 2-chloro-5-(pyridin-2-yl) pyrimidine via a Negishi cross-coupling

Perez-Balado, Carlos,Willemsens, Albert,Ormerod, Dominic,Aelterman, Wim,Mertens, Narda

, p. 237 - 240 (2012/12/26)

A practical and scaleable synthesis of 2-chloro-5-(pyridin-2-yl) pyrimidine, an intermediate in the synthesis of a selective PDE-V inhibitor, was developed. A Negishi cross-coupling between the in situ prepared 2-pyridylzinc chloride and 5-iodo-2-chloropyrimidine catalyzed by Pd(PPh3)4 afforded the product in one step. Development of a convenient purification did away with the necessity of chromatography, allowing the preparation of the product on kilogram scale.

Efange, Simon M. N.,Alessi, Elaine M.,Shih, H. C.,Cheng, Yung-Chi,Bardos, Thomas J.

, p. 904 - 910 (2007/10/02)

1-(2-Deoxy-β-D-ribofuranosyl)-5-bromo-2-pyrimidinone (BrPdR) and 1-(2-deoxy-β-D-ribofuranosyl)-5-iodo-2-pyrimidinone (IPdR) have been synthesized by condensation of the appropriate silylated bases 2a and 2b, respectively, with 3,5-bis-O-(p-chlorobenzoyl)-2-deoxy-α-D-ribofuranosyl chloride (8) in 1,2-dichloroethane, in the presence of SnCl4, followed by separation of the anomeric blocked nucleosides via column chromatography and subsequent deprotection with methanolic ammonia.Both BrPdR and IPdR exhibited significant antiherpes activities against various strains of HSV-1 and HSV-2, the latter compound (IPdR) showing the higher activity as well as the stronger binding to the virus-specific thimidine kinase.

α-Haloalkyl Ethers in Alkylations of 2-Pyrimidinones

Benneche, Tore,Undheim, Kjell

, p. 345 - 350 (2007/10/02)

The ambident 5-halopyrimidin-2-one anion with potassium as counterion in DMF is preferentially O-alkylated using the relatively hard α-chloroalkyl ether electrophiles.As ammonium salts in dichloromethane or by the use of KF-alumina in DME the preference is for N-alkylation.TMS ethers of the pyrimidinones are exclusively N-alkylated.
