The CAS Registry Mumber 16839-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16839-07:
(7*1)+(6*6)+(5*8)+(4*3)+(3*9)+(2*0)+(1*7)=129
129 % 10 = 9
So 16839-07-9 is a valid CAS Registry Number.
