25424-29-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25424-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,2 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25424-29:
(7*2)+(6*5)+(5*4)+(4*2)+(3*4)+(2*2)+(1*9)=97
97 % 10 = 7
So 25424-29-7 is a valid CAS Registry Number.

Some novel mesoionic bispurinone analogs: Studies on preparation and characterization
Mbagwu,Garland
, p. 571 - 573 (2007/10/02)
The preparation of the first examples of class II mesoionic bispurinones is described. Arylaminobithiazole 3 is cyclized by condensation with bis(2,4,6-trichlorophenyl) methylmalonate to yield anhydro3,3'-bis(6-methyl-8-aryl-5-hydroxy-7-oxothiazole[3,2-a]
