Check Digit Verification of cas no
The CAS Registry Mumber 673502-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,3,5,0 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 673502-34:
(8*6)+(7*7)+(6*3)+(5*5)+(4*0)+(3*2)+(2*3)+(1*4)=156
156 % 10 = 6
So 673502-34-6 is a valid CAS Registry Number.

Synthesis of New Substituted 2,3-Dihydro-1,4-dioxin-2-ones and 1,4-Dioxan-2-ones
Akopyan,Khachatryan
, p. 707 - 709 (2007/10/03)
3-Alkyl-6-methyl-2,3-dihydro-1,4-dioxin-2-ones reacted with acetyl chloride in the presence of zinc(II) chloride to give 5-acetyl-3-alkyl-6-methyl- 2,3-dihydro-l,4-dioxin-2-ones. Oxidation of the latter with hydrogen peroxide in formic acid, followed by treatment with magnesium bromide, afforded 3-alkyl-6-methyl-1,4-dioxane-2,5-diones. Chlorination of 6-hydroxymethyl-1,4- dioxan-2-ones with thionyl chloride and subsequent dehydrochlorination led to formation of 6-methylene-1,4-dioxan-2-ones.
