2918-80-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2918-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2918-80:
(6*2)+(5*9)+(4*1)+(3*8)+(2*8)+(1*0)=101
101 % 10 = 1
So 2918-80-1 is a valid CAS Registry Number.
