The CAS Registry Mumber 390-16-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 0 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 390-16: (5*3)+(4*9)+(3*0)+(2*1)+(1*6)=59 59 % 10 = 9 So 390-16-9 is a valid CAS Registry Number.
