The CAS Registry Mumber 2185-80-0 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 5 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2185-80: (6*2)+(5*1)+(4*8)+(3*5)+(2*8)+(1*0)=80 80 % 10 = 0 So 2185-80-0 is a valid CAS Registry Number.
