Check Digit Verification of cas no

The CAS Registry Mumber 1591-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1591-99:
(6*1)+(5*5)+(4*9)+(3*1)+(2*9)+(1*9)=97
97 % 10 = 7
So 1591-99-7 is a valid CAS Registry Number.

Palladium(0)-catalyzed carbon-Hydrogen bond functionalization for the synthesis of indoloquinazolinones

Tsukano, Chihiro,Okuno, Masataka,Nishiguchi, Hiromi,Takemoto, Yoshiji

supporting information, p. 1533 - 1538 (2014/06/09)

The indoloquinazolinone ring system has attracted considerable attention as a pharmacophore, because it shows various biological activities. The reported synthetic methods for the compound are simple and direct, but are not effective for the direct synthesis of indoloquinazolinone with a methylene group at the C-6 position. A palladium(0)-catalyzed cyclization of chloroquinazolinone via C-H functionalization was developed for a concise synthesis of indoloquinazolinone derivatives. The presence of a substituent at the C-6 position is important for obtaining the product in good yield. The conformation of the reaction intermediate, in particular the N-C-Pd bond angle, is important for the regioselectivity of the reaction.

Synthesis of new coumarin compounds and its hypoglycemic activity and structure-activity relationship

Qi, Gang,Zhang, Wenguo

, p. 9835 - 9839 (2014/01/06)

Novel coumarin compounds were designed and synthesized by combining the active moieties of hypoglycemic drugs. The coumarin compounds were made by sulfanilamide with isocynate, the intermediate sulfanilamide was formed from coumarin by chlorosulfonated and aminated. These targeted compounds were characterized by FT-IR, 1H NMR and MS spectra and their hypoglycemic activities were evaluated in mice. The preliminary results showed that some compounds exhibited evident hypoglycemic effect (P > 0.01, CMC-Na as negative control). The relationship between these compounds structure with their hypoglycemic activities were studied in order to design new antidiabetic agents.

Parasiticidal new substituted thienopyranones

-

, (2008/06/13)

Parasiticidal new substituted thienopyranones of the formula STR1 in which X represents O or S, R1 and R2 independently of one another represent hydrogen, halogen, CN, NO2, alkyl, aralkyl, aryl, alkylcarbonyl or alkoxycarbonyl, or, together with the adjacent C atoms, form a carbocyclic ring which is optionally interrupted by heteroatoms, R3 represents optionally substituted alkyl or phenyl, R4 represents hydrogen or alkyl, R3 and R4, together with the adjacent nitrogen atom, represent a heterocyclic 5- or 6-membered ring. Some of the intermediates for making them are also new.
