The CAS Registry Mumber 2989-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,8 and 9 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2989-16: (6*2)+(5*9)+(4*8)+(3*9)+(2*1)+(1*6)=124 124 % 10 = 4 So 2989-16-4 is a valid CAS Registry Number.
