The CAS Registry Mumber 138976-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,7 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138976-69:
(8*1)+(7*3)+(6*8)+(5*9)+(4*7)+(3*6)+(2*6)+(1*9)=189
189 % 10 = 9
