The CAS Registry Mumber 1985-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 5 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1985-89: (6*1)+(5*9)+(4*8)+(3*5)+(2*8)+(1*9)=123 123 % 10 = 3 So 1985-89-3 is a valid CAS Registry Number.
