Check Digit Verification of cas no

The CAS Registry Mumber 3505-67-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,0 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3505-67:
(6*3)+(5*5)+(4*0)+(3*5)+(2*6)+(1*7)=77
77 % 10 = 7
So 3505-67-7 is a valid CAS Registry Number.

179. Die Oxidation von 3-(1-Nitro-2-oxocycloalkyl)propanal

Zuercher, Alois,Hesse, Manfred

, p. 1937 - 1943 (2007/10/02)

Oxidation of the title compound 1 with KMnO4 under neutral condiitons led to the corresponding acid 2, 5-(2,3,4,5-tetrahydro-2-nitro-5-oxo-2-furyl)pentanoic acid (4), and 4-oxononadioic acid (6).On the basis of experimental results the mechanism of the formation of 4 is discussed (Scheme 1).Oxidation of 1 with KMnO4 under basic conditions gave 6 which was transformed to (E)-4,5-dihydro-5-(2'-oxocyclopentyliden)furan-2(3H)-one (12) with benzene/TsOH (Scheme 3).In contrast to this result the corresponding 4-oxoheptandioic acid (22) yields 1,6-dioxaspirononan-2,7-dione (23) only (Scheme 4).
