82731-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82731-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82731-52:
(7*8)+(6*2)+(5*7)+(4*3)+(3*1)+(2*5)+(1*2)=130
130 % 10 = 0
So 82731-52-0 is a valid CAS Registry Number.
