77953-97-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77953-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,5 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77953-97:
(7*7)+(6*7)+(5*9)+(4*5)+(3*3)+(2*9)+(1*7)=190
190 % 10 = 0
So 77953-97-0 is a valid CAS Registry Number.

DIASTEREOSELECTIVE SYNTHESIS OF CHROMAN SULFOXIDES
Akkerman, Jaap M.,Konig, Henk de,Huisman, Henderikus O.
, p. 797 - 801 (2007/10/02)
Intramolecular addition of a phenolic hydroxy function to α,β-unsaturated chiral sulfoxide led to the formation of a chiral chroman-sulfoxide in 22percent optical yield,.Subsequent conversions provided an α-tocopherol synthon in 12percent enantiomeric exc
