Check Digit Verification of cas no

The CAS Registry Mumber 19446-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,4 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19446-95:
(7*1)+(6*9)+(5*4)+(4*4)+(3*6)+(2*9)+(1*5)=138
138 % 10 = 8
So 19446-95-8 is a valid CAS Registry Number.

ALIPHATISCHE DIAZOVERBINDUNGEN. XI. SYNTHESE UND CYCLISIERUNG SELEN- BZW. TELLUR-HALTIGER ω-DIAZO-ACETOPHENONE ZU SELENO-BZW. TELLURO-3-CUMARANON

Lohner, W.,Praefcke, K

, p. 173 - 178 (1980)

The syntheses and chemical behaviour of ortho-butylseleno-and ortho-butyl-telluro-substituted ω-diazoacetophenones are described for the first time.Seleno- and telluro-3-coumaranone are obtained by novel routes involving cyclization of these diazoketones.

LITHIUM DISELENIDE IN APROTIC MEDIUM - A CONVENIENT REAGENT FOR SYNTHESIS OF ORGANIC DISELENIDES

Syper, Ludwik,Mlochowski, Jacek

, p. 6119 - 6130 (2007/10/02)

The reduction of selenium with lithium in THF in the presence of diphenylacetylene as a catalyst afforded lithium diselenide, which reacted with electrophiles giving alkyl or aryl diselenides 1 - 3 and selenides 4, as by-products.The useful method for preparation of diselenides based on this reaction was elaborated.
