88681-85-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88681-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,6,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88681-85:
(7*8)+(6*8)+(5*6)+(4*8)+(3*1)+(2*8)+(1*5)=190
190 % 10 = 0
So 88681-85-0 is a valid CAS Registry Number.

KETAL CLAISEN REARRANGEMENTS OF FUNCTIONALIZED KETALS
Daub, G. WIlliam,Lunt, Sharon R.
, p. 4397 - 4400 (1983)
Functionalized ketals participate successfully in the acid-catalyzed ketal Claisen rearrangement to afford mixtures of the isomeric γ,δ-unsaturated ketones, with the more highly substituted isomer predominating by a factor of 2-4:1.
