Check Digit Verification of cas no
The CAS Registry Mumber 21758-86-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,5 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21758-86:
(7*2)+(6*1)+(5*7)+(4*5)+(3*8)+(2*8)+(1*6)=121
121 % 10 = 1
So 21758-86-1 is a valid CAS Registry Number.

Condensation of α-mercaptomethylpyridine with 1,4-naphthoquinone, 2-chloro-1,4-naphthoquinone and 2,3-dichloro-1,4-naphthoquinone leads to a number of quinonoid derivatives including the desired 2-α-pyridylmethylmercapto-1,4-naphthoquinone (XVI) and its 3-chloro derivative (XI).Cyclization of XVI and XI gives 3,4-phthaloyl-2-thiaquinolizine (I) which represents a new heterocyclic quinonoid chromophoric system.Plausible mechanisms for the formation of the different heterocyclic quinones are discussed.Interaction of 1,4-naphthoquinone with 1-mercaptomethylisoquinoline affords 8,9-benzo-3,4-phthaloyl-2-thiaquinolizine (XXI).The thiaquinolizines undergo sulphur extrusion on heating to m.p. or on treatment with alkaline dithionite to yield the corresponding 2,3-phthaloylpyrrocolines.
