The CAS Registry Mumber 138943-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138943-36:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*3)+(2*3)+(1*6)=159
159 % 10 = 9
So 138943-36-9 is a valid CAS Registry Number.
