The CAS Registry Mumber 84176-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 84176-25: (7*8)+(6*4)+(5*1)+(4*7)+(3*6)+(2*2)+(1*5)=140 140 % 10 = 0 So 84176-25-0 is a valid CAS Registry Number.
