The CAS Registry Mumber 1985-99-5 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, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1985-99: (6*1)+(5*9)+(4*8)+(3*5)+(2*9)+(1*9)=125 125 % 10 = 5 So 1985-99-5 is a valid CAS Registry Number.
