Check Digit Verification of cas no

The CAS Registry Mumber 89402-42-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89402-42:
(7*8)+(6*9)+(5*4)+(4*0)+(3*2)+(2*4)+(1*2)=146
146 % 10 = 6
So 89402-42-6 is a valid CAS Registry Number.

Bitopertin synthetic method and intermediate

-

Paragraph 0061; 0064; 0065, (2018/03/26)

The present invention discloses a new synthesis method and intermediates of Bitopertin. According to the Bitopertin synthesis method, 5-methylsulfonyl-2-[(1S)-2,2,2-trifluoro-1-methylethoxy]benzoic acid is adopted as a raw material, and continuous multi-step operations such as chlorination, acylation, deprotection, condensation and re-crystallization are subjected to performed to obtain the Bitopertin, wherein the intermediates in each step do not require further purification, and the total yield can achieve more than or equal to 80%.

Process for the preparation of fluorinated pyridine derivatives

-

, (2008/06/13)

In accordance with a novel process, 2,3-difluoropyridines of formula I STR1 wherein X is halogen or trifluoromethyl, are prepared by diazotising a 3-amino-2-halopyridine of formula II STR2 wherein X is as defined for formula I and Y is bromine, chlorine or fluorine, in the presence of hydrogen fluroide, to give a 3-fluoro-2-halopyridine of formula III STR3 wherein X and Y are as defined for formula II, and treating resultant 3-fluoro-2-halopyridines of formula III, wherein Y is bromine or chlorine, with a fluorinating agent. The 2,3-difluoropyridines prepared by the novel process are valuable intermediates for the preparation of 2-[4-(3-fluoropyridin-2-yloxy)-phenoxy]propionic acid derivatives which are known as herbicides.

2,3-Difluoro-5-(trifluoromethyl)pyridine and methods of making and using the same

-

, (2008/06/13)

Novel 2,3-difluoro-5-(trifluoromethyl)pyridine is prepared by fluorinating 3-chloro-2-fluoro-5-(trifluoromethyl)pyridine under favorable conditions. The compound is useful as a chemical intermediate in the preparation of herbicides.
