275377-30-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 275377-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,5,3,7 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 275377-30:
(8*2)+(7*7)+(6*5)+(5*3)+(4*7)+(3*7)+(2*3)+(1*0)=165
165 % 10 = 5
So 275377-30-5 is a valid CAS Registry Number.

Synthesis of 2,2-difluoro-homoallylic alcohols via ring-opening of gem-difluorocyclopropane and aerobic oxidation by photo-irradiation in the presence of an organic pigment

Takenaka, Hiroaki,Masuhara, Yoshihiro,Narita, Kent,Nokami, Toshiki,Itoh, Toshiyuki

, p. 6106 - 6114 (2018/09/06)

We found that aerobic oxidation took place after the visible light-mediated ring-opening reaction of gem-difluorocyclopropane in the presence of an organic dye and amine to furnish 2,2-difluoro-homoallylic alcohols in good yields.

Synthesis of 4,4-difluoroglycosides using ring-closing metathesis

Audouard, Christophe,Fawcett, John,Griffiths, Gerry A.,Percy, Jonathan M.,Pintat, Stephane,Smith, Clive A.

, p. 528 - 541 (2007/10/03)

4-Deoxy-4,4-difluoro-glycosides have been synthesised for the first time via a direct sequence involving ring-closing metathesis and indium-mediated difluoroallylation with 1-bromo-1,1-difluoropropene in water. Two protecting group strategies were explore
