Check Digit Verification of cas no
The CAS Registry Mumber 125219-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,1 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125219-61:
(8*1)+(7*2)+(6*5)+(5*2)+(4*1)+(3*9)+(2*6)+(1*1)=106
106 % 10 = 6
So 125219-61-6 is a valid CAS Registry Number.

CYCLIZATION OF NITRILES. XXXIII. SYNTHESIS AND STRUCTURE OF 4-ARYL-2,6-DIAMINO-3,5-DICYANOTHIOPYRANS AND THEIR RECYCLIZATION TO 6-AMINO-4-ARYL-3,5-DICYANO-2(1H)-PYRIDINETHIONES

Like the three-component condensation of aromatic aldehydes, malononitrile, and cyanothioacetamide, the reaction of arylidenemalononitriles with cyanothioacetamide and of arylidenecyanothioacetamides with malononitrile leads to the formation of 4-aryl-2,6-diamino-3,5-dicyano-4H-thiopyrans.It was established by x-ray crystallographic investigation that the 4H-thiopyran ring in the obtained compounds has the boat conformation.Under the influence of bases the 4H-thiopyrans readily undergo recyclization to 6-amino-4-aryl-3,5-dicyano-2(1H)-pyridinethiones.
