1639904-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1639904-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,9,0 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1639904-68:
(9*1)+(8*6)+(7*3)+(6*9)+(5*9)+(4*0)+(3*4)+(2*6)+(1*8)=209
209 % 10 = 9
So 1639904-68-9 is a valid CAS Registry Number.

Pyrido[2,3-d]pyrimidines: A novel tandem Michael Cyclization of 6-aminouracils with arylidenecyanoacetate using BiCl3

Suresh, Subhash Chand,Sandhu, Jagir S.

, p. 728 - 732 (2014/07/07)

1,3-Dimethyl-2,4,7-trioxo-5-aryl-1,2,3,4,7,8-hexahydropyrido[2,3-d] pyrimidine-6-carbonitriles have been synthesized via tandem Michael-Cyclization of 6-aminouracils with arylidene ethylcyanoacetates employing catalytic amount of BiCl3. Under mild reaction conditions, pyrido[2,3-d]pyrimidines have been obtained in very good yields in one pot.
