The CAS Registry Mumber 71553-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,5 and 3 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 71553-85: (7*7)+(6*1)+(5*5)+(4*5)+(3*3)+(2*8)+(1*5)=130 130 % 10 = 0 So 71553-85-0 is a valid CAS Registry Number.
