2180-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2180-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2180-68:
(6*2)+(5*1)+(4*8)+(3*0)+(2*6)+(1*8)=69
69 % 10 = 9
So 2180-68-9 is a valid CAS Registry Number.
