132216-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132216-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,1 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132216-34:
(8*1)+(7*3)+(6*2)+(5*2)+(4*1)+(3*6)+(2*3)+(1*4)=83
83 % 10 = 3
So 132216-34-3 is a valid CAS Registry Number.

Zur Synthese von 9,9-Dimethyl-2-oxa-bicyclononan
Spreitzer, Helmut
, p. 847 - 851 (2007/10/02)
The diketone 1 undergoes base induced ring opening to the δ-ketoacid 2a.Subsequent stereoselective reduction of the carbonyl-group affords the corresponding hydroxyacid 4a and condensation leads to the bicyclic lactone 5 which can be reduced to the title
