66478-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66478-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,7 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66478-46:
(7*6)+(6*6)+(5*4)+(4*7)+(3*8)+(2*4)+(1*6)=164
164 % 10 = 4
So 66478-46-4 is a valid CAS Registry Number.

DIISOPROPOXY- AND DI-tert-BUTOXYETHYNE STABLE ACETYLENE DIETHERS
Bou, Anna,Pericas,Miquel A.,Serratosa, Felix
, p. 1441 - 1449 (2007/10/02)
The rather stable acetylene diethers diisopropoxy- and di-t-butoxyethyne are prepared either from glyoxal or dioxane.Catalytic hydrogenation, acid-catalyzed hydration and formation of the corresponding hexacarbonyl dicobalt complexes are reported.
