The CAS Registry Mumber 123518-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,1 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123518-02:
(8*1)+(7*2)+(6*3)+(5*5)+(4*1)+(3*8)+(2*0)+(1*2)=95
95 % 10 = 5
So 123518-02-5 is a valid CAS Registry Number.

CYCLIZATION OF NITRILES. XXX. SYNTHESIS, STRUCTURE, AND PROPERTIES OF 6-AMINO-4-ARYL(HETEROARYL)-3,5-DICYANO-2(1H)-PYRIDINETHIONES

Sharanin, Yu. A.,Promomenkov, V. N.,Shestopalov, A. M.,Nestorov, V. N.,Malenchuk, S. N.,et al.

, p. 560 - 565 (2007/10/02)

The reactions of arylmethylenecyanothioacetamides with malononitrile and of arylmethylenemalononitriles with cyanothioacetamide take place regioselectively with the formation of 6-amino-4-aryl-3,5-dicyano-2(1H)-pyridinethiones and not 5-arylmethylene-4,6-diamino-3-cyanopyridine-2-thiones.The 6-amino-4-aryl-3,5-dicyano-2(1H)-pyridinethiones are formed by the recyclization of the 4-aryl-2,6-diamino-3,5-dicyano-4H-thiopyranes.
