104654-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104654-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,5 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104654-71:
(8*1)+(7*0)+(6*4)+(5*6)+(4*5)+(3*4)+(2*7)+(1*1)=109
109 % 10 = 9
So 104654-71-9 is a valid CAS Registry Number.

EFFICIENT SYNTHESIS OF SOME 2-OXASPIRONONA-1-ONES AS ANISATIN MODELS
Kato, Michiharu,Kitahara, Haruo,Yoshikoshi, Akira
, p. 1785 - 1788 (2007/10/02)
As a model study for the synthesis of anisatin, 2-oxaspirononane and 5-hydroxy-5-methyl-2-oxaspirononane were synthesized from methyl cyclohexanecarboxylate and 2-ethoxycarbonylcyclohexanone, respectively, and these oxenates were submitted to ru
