Check Digit Verification of cas no

The CAS Registry Mumber 1081-68-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1081-68:
(6*1)+(5*0)+(4*8)+(3*1)+(2*6)+(1*8)=61
61 % 10 = 1
So 1081-68-1 is a valid CAS Registry Number.

SCHWEFELVERBINDUNGEN DES ERDOELS XV. METHYL-5,6,7,8-TETRAHYDRODINAPHTHOTHIOPHENE UND METHYLDINAPHTHOTHIOPHENE

Boberg, Friedrich,Jachiewicz, Adam,Garming, Alfons

, p. 1 - 12 (2007/10/02)

A one pot synthesis gives methyl-5,6,7,8-tetrahydrodinaphthothiophenes (7) from methyl-1,2,3,4-tetrahydronaphthalen-1-ones (1) by bromination and sulfurization.Tetrahydro compounds 7 have been dehydrogenated to corresponding dinaphthothiophenes 8.Proofs for the constitutions are nmr data of 7, 8 and the independent synthesis of one compound 8.A reaction mechanism with 1,4-dithiine intermediates is discussed. Key words: Alkyl-1,2,3,4-tetrahydronaphthalen-1-ones; alkyl-5,6,7,8-tetrahydrodinaphthothiophenes; alkyldinaphthothiophenes; dehydrogenation with o-chlorobenzoquinone.
