Check Digit Verification of cas no

The CAS Registry Mumber 917771-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,7,7 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917771-50:
(8*9)+(7*1)+(6*7)+(5*7)+(4*7)+(3*1)+(2*5)+(1*0)=197
197 % 10 = 7
So 917771-50-7 is a valid CAS Registry Number.

PROLINE AMIDE COMPOUNDS AND THEIR AZETIDINE ANALOGUES CARRYING A SPECIFICALLY SUBSTITUTED BENZYL RADICAL

-

Page/Page column 74; 75, (2018/10/19)

The present invention relates to proline amide compounds and their azetidine derivatives of formula I wherein the variables are as defined in the claims and the description. The invention further relates to a pharmaceutical composition containing such compounds, to their use as modulators, especially agonists or partial agonists, of the 5-HT2C receptor, their use for preparing a medicament for the prevention or treatment of conditions and disorders which respond to the modulation of 5-HT2C receptor, to a method for preventing or treating conditions and disorders which respond to the modulation of the 5-HT2C receptor, and processes for preparing such compounds and compositions.

Synthesis of fluorinated cycloalkyl N-phenylcarbamates and their microbial defluorination/oxygenation by Beauveria bassiana

Haufe, Guenter,Pietz, Sylke,Woelker, Doerthe,Froehlich, Roland

, p. 2166 - 2175 (2007/10/03)

Earlier investigations showed that cycloalkyl N-phenylcarbamates were hydroxylated by the fungus Beauveria bassiana predominantly in the 4-position relative to the electron-rich substituent. In cases involving fluorinated methylene groups potentially capable of hydroxylation, however, defluorination and formation of a ketone was observed. The formation of the ketone can be explained by primary hydroxylation to forman unstable geminal fluorohydrin, which is subsequently dehydrofluorinated. Wiley-VCH Verlag GmbH & Co.
