Check Digit Verification of cas no

The CAS Registry Mumber 94833-73-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,3 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94833-73:
(7*9)+(6*4)+(5*8)+(4*3)+(3*3)+(2*7)+(1*3)=165
165 % 10 = 5
So 94833-73-5 is a valid CAS Registry Number.

CYCLIZATION OF NITRILES. X. ENAMINO NITRILES OF THE 1,3-DITHIA-4-CYCLOHEXENE SERIES AND THEIR RECYCLIZATION TO DERIVATIVES OF PYRIDINE AND THIAZOLE

Sharanin, Yu. K.,Shestopalov, A. M.,Promonenkov, V. K.,Rodinovskaya, L. A.

, p. 1402 - 1415 (2007/10/02)

The recyclization of 4-amino-6-aryl-5-cyano-2-cyclopentane(cyclohexane)spiro-1,3-dithia-4-cyclohexenes, obtained from gem-dithiols and arylidenemalononitriles, leads to the formation of 4-aryl-5,6-polymethylene-3-cyano-2-(1H)-pyridinethiones.The latter are used in the synthesis of various 3-aminothienopyridines, 4-aryl-3-amino-5,6,7,8-tetrahydrothienoquinolines, and other heterocyclic compounds condensed with quinoline. 1-Cyano-1-(4-aryl-2-thiazolyl)-2-arylethylenes were obtained by the reaction of the 1,3-dithia-4-cyclohexenes with phenacyl bromides.
