Check Digit Verification of cas no

The CAS Registry Mumber 2127-04-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2127-04:
(6*2)+(5*1)+(4*2)+(3*7)+(2*0)+(1*4)=50
50 % 10 = 0
So 2127-04-0 is a valid CAS Registry Number.

Heterocyclic Quinonoid Chromophoric Systems : Part V - Synthesis of 3,4-Phthaloyl-2-thiaquinolizine

Shah, J. N.,Tilak, B. D.

, p. 29 - 36 (2007/10/02)

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.
