132969-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132969-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,6 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132969-69:
(8*1)+(7*3)+(6*2)+(5*9)+(4*6)+(3*9)+(2*6)+(1*9)=158
158 % 10 = 8
So 132969-69-8 is a valid CAS Registry Number.

A stereoselective route to the spirobicyclic ring system of oscillatoxin D
Walkup,Boatman Jr.,Kane,Cunningham
, p. 3937 - 3940 (2007/10/02)
Using a model system, a stereoselective assembly of the 1-oxaspiro[5.5]undec-4-ene-8-one ring system of the antileukemic natural products oscillatoxin D and 30-methyloscillatoxin D was demonstrated. A key step was an intramolecular attack of the C1/
