91899-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91899-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91899-77:
(7*9)+(6*1)+(5*8)+(4*9)+(3*9)+(2*7)+(1*7)=193
193 % 10 = 3
So 91899-77-3 is a valid CAS Registry Number.

The Effect of Lewis Acid and Solvent on Concerted 1,2-Acyl Migration
Bach, Robert D.,Domagala, John M.
, p. 4181 - 4188 (2007/10/02)
Lewis acid catalyzed 1,2-benzoyl migration in (E)- and (Z)-1,3-diphenyl-2-buten-1-on oxides (dypnone oxides) is a concerted process that occurs with inversion of configuration at the migration terminus when nonpolar solvents are employed.In methanol solve
