Check Digit Verification of cas no

The CAS Registry Mumber 1421-82-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1421-82:
(6*1)+(5*4)+(4*2)+(3*1)+(2*8)+(1*2)=55
55 % 10 = 5
So 1421-82-5 is a valid CAS Registry Number.

Synthesis, absolute configuration, and bacterial mutagenicity of the 8 stereoisomeric vicinal diol epoxides at the terminal benzo ring of carcinogenic dibenz[ a,h ]anthracene

Frank, Heinz,Funk, Mario,Oesch, Franz,Platt, Karl L.

experimental part, p. 2258 - 2268 (2012/06/15)

The synthesis of the 8 possible stereoisomeric diol epoxides (DEs) at the terminal benzo ring of carcinogenic dibenz[a,h]anthracene (DBA) is reported. trans-3,4-Dihydroxy-3,4-dihydro-DBA (1) afforded the 4 bay region DEs: the enantiomeric pairs of the ant

Synthesis of Biologically Active Metabolites of Dibenzanthracene

Lee, Hong Mee,Harvey, Ronald G.

, p. 588 - 592 (2007/10/02)

Syntheses are described of the trans 1,2- and 3,4-dihydro diol metabolites (3a and 1a) of dibenzanthracene (DBA) and the corresponding diol epoxide derivatives 4 and 2, implicated as the ultimate carcinogenic metabolites of DBA.The synheses of 1a and 3a are accomplished from DBA via lithium-ammonia reduction to 1,4,7,8,11,14-hexahydrodibenzanthracene, base-catalyzed isomerization, Prevost reaction, dehydrogenation, and basic methanolysis.This approach involves considerably fewer steps and affords superior overall yields than obtainable by more conventional methods entailing multistep ring construction.Epoxidation of 1a affords stereospecifically the anti diol epoxide isomer 2, whereas similar reaction of 3a furnishes a mixture of the corresponding syn and anti diol epoxide isomers in 3:1 ratio.Biological evidence implicates 1a and 2 as proximate and ultimate carcinogenic forms, respectively, of DBA.Synthesis of 3-hydroxydibenzanthracene, also known to be a metabolite of DBA, is also described.
