The CAS Registry Mumber 201280-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,8 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201280-69:
(8*2)+(7*0)+(6*1)+(5*2)+(4*8)+(3*0)+(2*6)+(1*9)=85
85 % 10 = 5
So 201280-69-5 is a valid CAS Registry Number.

Acetoacetanilides in synthesis of 4-aryl-5-arylcarbamoyl-6-methyl-s-cyanopyridine-2(1H)-thiones

Dyachenko,Krivokolysko,Litvinov

, p. 481 - 488 (1997)

The reaction of acetoacetanilides with arylmethylenecyanothioacetamides leads to 4-aryl-5-arylcarbamoyl-6-methyl-3-cyanopyridine-2(1H)-thiones, based on which we have obtained substituted 2-alkylthiopyridines and thieno[2,3-b]pyridines. 1997 Plenum Publishing Corporation.
