159730-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 159730-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,3 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159730-67:
(8*1)+(7*5)+(6*9)+(5*7)+(4*3)+(3*0)+(2*6)+(1*7)=163
163 % 10 = 3
So 159730-67-3 is a valid CAS Registry Number.

Photoswitchable sensitization of porphyrin excited states

Straight, Stephen D.,Terazono, Yuichi,Kodis, Gerdenis,Moore, Thomas A.,Moore, Ana L.,Gust, Devens

, p. 170 - 174 (2006)

Light-driven molecular switches consisting of a porphyrin covalently linked to a fulgimide photochrome antenna have been prepared. Light absorbed by the cyclic form of the fulgimide is transferred to the porphyrin with ? 95% efficiency, generating the por

Synthesis of α,α-difluoro-β-amino esters or gem-difluoro-β-lactams as potential metallocarboxypeptidase inhibitors

Boyer, Nicolas,Gloanec, Philippe,De Nanteuil, Guillaume,Jubault, Philippe,Quirion, Jean-Charles

experimental part, p. 4277 - 4295 (2009/04/10)

The synthesis of gem-difluorinated β-lactams and gem-difluorinated β-amino acids, each possessing a potential basic functional group, from ethyl bromodifluoroacetate and either imines (for β-lactams) or N-(α-aminoalkyl)benzotriazoles (for β-amino esters) was investigated. A series of these compounds were used for the design of novel metallocarboxypeptidase inhibitors. N-Alkylation and N-acylation of these two versatile scaffolds were carried out, leading to the expected targets in moderate to good yields. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
