99347-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99347-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,4 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99347-03:
(7*9)+(6*9)+(5*3)+(4*4)+(3*7)+(2*0)+(1*3)=172
172 % 10 = 2
So 99347-03-2 is a valid CAS Registry Number.

Some 1-phenyl-1H-6-(un)substituted-5-substituted-arylpyrazolopyrimidine-4(5H)-ones are synthesized by transformation of 6-methyl-1-phenyl-1H-pyrazolooxazin-4-ones and also from 5-amino-4-carbethoxy-1-phenyl pyrazole.
