80359-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80359-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80359-85:
(7*8)+(6*0)+(5*3)+(4*5)+(3*9)+(2*8)+(1*5)=139
139 % 10 = 9
So 80359-85-9 is a valid CAS Registry Number.

Regioselectivity of the Ketal Claisen Rearrangement
Daub, G. William,Sanchez, Michael G.,Cromer, Robbin A.,Gibson, Lester L.
, p. 743 - 745 (2007/10/02)
The ketal Claisen rearrangement with a simple unsymmetrical ketal exhibits a high degree of regioselectivity, which is attenuated by substitution of the α- and β-carbon atoms of the ketal.
