6226-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6226-80-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6226-80:
(6*6)+(5*2)+(4*2)+(3*6)+(2*8)+(1*0)=88
88 % 10 = 8
So 6226-80-8 is a valid CAS Registry Number.
