The CAS Registry Mumber 289652-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,5 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 289652-31:
(8*2)+(7*8)+(6*9)+(5*6)+(4*5)+(3*2)+(2*3)+(1*1)=189
189 % 10 = 9
So 289652-31-9 is a valid CAS Registry Number.
