82505-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82505-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,0 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82505-85:
(7*8)+(6*2)+(5*5)+(4*0)+(3*5)+(2*8)+(1*5)=129
129 % 10 = 9
So 82505-85-9 is a valid CAS Registry Number.
