Check Digit Verification of cas no

The CAS Registry Mumber 91899-75-1 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 91899-75:
(7*9)+(6*1)+(5*8)+(4*9)+(3*9)+(2*7)+(1*5)=191
191 % 10 = 1
So 91899-75-1 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
