The CAS Registry Mumber 89975-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,7 and 5 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 89975-69: (7*8)+(6*9)+(5*9)+(4*7)+(3*5)+(2*6)+(1*9)=219 219 % 10 = 9 So 89975-69-9 is a valid CAS Registry Number.
