The CAS Registry Mumber 85689-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 85689-38:
(7*8)+(6*5)+(5*6)+(4*8)+(3*9)+(2*3)+(1*8)=189
189 % 10 = 9
So 85689-38-9 is a valid CAS Registry Number.
