The CAS Registry Mumber 138469-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,6 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138469-69:
(8*1)+(7*3)+(6*8)+(5*4)+(4*6)+(3*9)+(2*6)+(1*9)=169
169 % 10 = 9
