4727-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4727-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4727-93:
(6*4)+(5*7)+(4*2)+(3*7)+(2*9)+(1*3)=109
109 % 10 = 9
So 4727-93-9 is a valid CAS Registry Number.

2-Oxo-1,3,2-dioxathianes. I. Preparation of the Alkyl-substituted Derivatives

Virtanen, Terttu,Nikander, Hannu

, p. 113 - 116 (2007/10/02)

2-Oxo-1,3,2-dioxathiane, all methyl- and several other alkyl-substituted 2-oxo-1,3,2-dioxathianes have been synthesized by condensing 1,3-alkanediols and thionyl chloride.The amount of the S==O-axial and S==O-equatorial isomers can be controlled by adding pyridine to the reaction mixture.
