Check Digit Verification of cas no

The CAS Registry Mumber 169053-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,0,5 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 169053-02:
(8*1)+(7*6)+(6*9)+(5*0)+(4*5)+(3*3)+(2*0)+(1*2)=135
135 % 10 = 5
So 169053-02-5 is a valid CAS Registry Number.

New approach to the synthesis of dibenzodithia- and benzothiaazacrown ethers via the aromatization of 2-alkylthio(arylthio)-cyclohexanes during bromination

Kudryatsev,Samofin

, p. 106 - 111 (2007/10/03)

A new scheme for the synthesis of dibenzodithiacrown ethers is proposed based on the use of substituted phenol derivatives as intermediates, prepared by aromatization of 2-alkylthio(arylthio)cyclohexanes during bromination. 1,7-Dithia-8,9,17,18-dibenzo-18-crown-6 and 1,10-dithia-11,12,20,21-dibenzo-21-crown-7 without isomers relative to position of the sulfur atoms have been synthesized, and also new thiadiazamacroheterocycles - 1,4,7-trioxa-10,19-dithia-13,16-diaza-12,17-dioxo-8,9,14,15,20,21- tribenzoheneicosane and 1,4,7,10-tetraoxa-13,22-dithia-16,19-diaza-15,20-dioxo-11,12,17,18,23,24- tribenzotetracosane. 1997 Plenum Publishing Corporation.
