Check Digit Verification of cas no
The CAS Registry Mumber 679391-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,9,3,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 679391-85:
(8*6)+(7*7)+(6*9)+(5*3)+(4*9)+(3*1)+(2*8)+(1*5)=226
226 % 10 = 6
So 679391-85-6 is a valid CAS Registry Number.

Regioselective synthesis of 1,7-dioxaspiro[4.4]nonanes from a trimethylenemethane dianion synthon
Alonso, Francisco,Dacunha, Bruno,Meléndez, Jaisiel,Yus, Miguel
, p. 3437 - 3450 (2007/10/03)
2-Chloromethyl-3-(2-methoxyethoxy)prop-1-ene behaves as a versatile trimethylenemethane dianion synthon, precursor of a variety of methylidenic diols obtained by DTBB-catalysed lithiation in the presence of a carbonyl compound (E1=R1R2CO) in THF at -78 to 0°C, followed by the addition of an epoxide [E2=R3R 4C(O)CHR5] at 0 to 20°C and final hydrolysis. These diols undergo double intramolecular iodoetherification in the presence of iodine and silver(I) oxide in THF or dioxane-water, to give the corresponding 1,7-dioxaspiro[4.4]nonanes, which can be easily oxidised to a variety of 1,7-dioxaspiro[4.4]nonan-6-ones. These skeletons are present in a wide series of natural products.
