Check Digit Verification of cas no

The CAS Registry Mumber 123331-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,3 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123331-78:
(8*1)+(7*2)+(6*3)+(5*3)+(4*3)+(3*1)+(2*7)+(1*8)=92
92 % 10 = 2
So 123331-78-2 is a valid CAS Registry Number.

Ozonolyse von Olefinen, III: Saeurekatalysierte Ozonolyse von 3-Hexen-1,6- und 2-Penten-1,5-dicarbonylderivaten

Poklukar, Norbert,Mittelbach, Martin

, p. 203 - 207 (2007/10/02)

The ozonolysis of mono-unsaturated compounds containing the structural element =CH-CH2-R was investigated.Reductive ozonolysis of (E)-3-hexene-1,6-dioic acid gives methyl 3,3-dimethoxypropanoate (2), whereas ozonolysis of dimethyl (E)-3-hexene-1,6-dioate (1a) and (Z)-1,1,6,6-tetramethoxy-3-hexene (1b) in a methanolic solution of HCl leads to a mixture of 2, dimethyl malonate (3a) and 1,1,3,3-tetramethoxypropane (3b).The homologuos derivatives, dimethyl glutaconate (4a) and 1,1,5,5-tetramethoxy-2-pentene (4b), were ozonized to give mixtures of 2, 3, dimethyl oxalate (5), methyl 2,2-dimethoxyacetate (6a), and 1,1,2,2-tetramethoxyethane (6b).The ratios of the various reaction products were determined by gas chromatography.In each case the formation of the bifunctional derivatives 2 and 6a was favoured.
