1243055-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243055-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,0,5 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243055-57:
(9*1)+(8*2)+(7*4)+(6*3)+(5*0)+(4*5)+(3*5)+(2*5)+(1*7)=123
123 % 10 = 3
So 1243055-57-3 is a valid CAS Registry Number.

Synthesis of novel oxindolylpyrrolo[2,3-d]pyrimidines via a three-component sequential tandem reaction
Rad-Moghadam, Kurosh,Azimi, Seyyedeh Cobra
, p. 9706 - 9712 (2012/11/07)
A novel one-pot three-component reaction of 6-amino-uracil, isatin, and acetophenone was accomplished through a programmed pH variation for the synthesis of 5-(2-oxoindolin-3-yl)-1H-pyrrolo[2,3-d]pyrimidine-2,4(3H,7H)-dione derivatives. The reaction was c
