7256-82-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7256-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,5 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7256-82:
(6*7)+(5*2)+(4*5)+(3*6)+(2*8)+(1*2)=108
108 % 10 = 8
So 7256-82-8 is a valid CAS Registry Number.
