247080-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247080-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,8 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 247080-04:
(8*2)+(7*4)+(6*7)+(5*0)+(4*8)+(3*0)+(2*0)+(1*4)=122
122 % 10 = 2
So 247080-04-2 is a valid CAS Registry Number.

Synthesis of 1,3,2-dioxathiolane-4-methylene-2-oxides: Potential allene oxide equivalents
Shipman, Michael,Thorpe, Heidi R.,Clemens, Ian R.
, p. 10845 - 10850 (2007/10/03)
Two complementary approaches to 1,3,2-dioxathiolane-4-methylene-2-oxides are described. For example, treatment of 2-hydroxy-2-methylbutan-3-one with thionyl chloride (Et3N, CH2Cl2, -78°C) yields 5.5-dimethyl-1,3,2- dioxath
