Check Digit Verification of cas no

The CAS Registry Mumber 190664-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,6,6 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 190664-22:
(8*1)+(7*9)+(6*0)+(5*6)+(4*6)+(3*4)+(2*2)+(1*2)=143
143 % 10 = 3
So 190664-22-3 is a valid CAS Registry Number.

Ketene acetals from thermolysis of aryloxy methoxy oxadiazolines. Evidence for carbonyl ylide intermediates

Couture, Philippe,El-Saidi, Manal,Warkentin, John

, p. 326 - 332 (1997)

Thermolysis of oxadiazolines (5) in benzene at 110°C leads to ketene acetals (11) as minor products. Carbonyl ylide intermediates (6), and oxiranes (7), presumably in equilibrium with those ylides, are implicated as unstable precursors of the ketene aceta
