7202-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7202-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,0 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7202-71:
(6*7)+(5*2)+(4*0)+(3*2)+(2*7)+(1*1)=73
73 % 10 = 3
So 7202-71-3 is a valid CAS Registry Number.
