Check Digit Verification of cas no

The CAS Registry Mumber 192070-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,0,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 192070-57:
(8*1)+(7*9)+(6*2)+(5*0)+(4*7)+(3*0)+(2*5)+(1*7)=128
128 % 10 = 8
So 192070-57-8 is a valid CAS Registry Number.

Reactions of α,β-enones with diazo compounds, 2: Synthesis of dihydrofuran derivatives

Anac, Olcay,Daut, Ayse

, p. 1249 - 1254 (1997)

Several α,β-unsaturated ketones were treated with dimethyl diazomalonate and ethyl acetodiazoacetate under bis(acetylacetonato)copper(II) catalysis. Dihydrofuran derivatives, obviously arising from carbonyl ylides, were isolated in high yields. Structural identifications were carried out using 2D-NMR-spectroscopic data.
