127441-14-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127441-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,4 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127441-14:
(8*1)+(7*2)+(6*7)+(5*4)+(4*4)+(3*1)+(2*1)+(1*4)=109
109 % 10 = 9
So 127441-14-9 is a valid CAS Registry Number.

Synthesis of 2,3-substituted tetrahydropyrans by rearrangement of 5,6-dihydro-4H-1,3-dioxocins
Frauenrath,Sawicki
, p. 649 - 650 (2007/10/02)
The synthesis of 5,8-dihydro-4H-1,3-dioxocins 2 and 5,6-dihydro-4H-1,3-dioxocins 3 is described. 2-Substituted tetrahydropyran-3-carbaldehydes are obtained by acid-catalyzed rearrangement of 3.
