The CAS Registry Mumber 2117-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 7 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2117-73: (6*2)+(5*1)+(4*1)+(3*7)+(2*7)+(1*3)=59 59 % 10 = 9 So 2117-73-9 is a valid CAS Registry Number.
