Check Digit Verification of cas no

The CAS Registry Mumber 30804-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,8,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30804-34:
(7*3)+(6*0)+(5*8)+(4*0)+(3*4)+(2*3)+(1*4)=83
83 % 10 = 3
So 30804-34-3 is a valid CAS Registry Number.

Oxidation of Aromatic Compounds. VI. Oxidation of Unsymmetrical Diarylacetylenes in the CF3COOH-CH2Cl2-PbO2 System

Vasil'ev,Rudenko

, p. 1555 - 1584 (2007/10/03)

Oxidation of unsymmetrical diarylacetylenes ArC≡CAr′ in the CF3COOH-CH2Cl2-PbO2 system at 0-2°C in 1-3 h yields either pure 1,2,3,4-tetraaryl-2-butene-1,4-diones or mixtures of three isomeric γ-di-ketones Ar(Ar′CO)C=C(COAr′)Ar, Ar′(ArCO)C=C(COAr)Ar′, and Ar′(ArCO)C=C(COAr′)Ar which are predominantly Z isomers. The effect of electronic properties of the substituents in diarylacetylenes on the regio- and stereoselectivity of the reaction is discussed.
