The CAS Registry Mumber 817208-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,7,2,0 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 817208-25:
(8*8)+(7*1)+(6*7)+(5*2)+(4*0)+(3*8)+(2*2)+(1*5)=156
156 % 10 = 6
So 817208-25-6 is a valid CAS Registry Number.
