The CAS Registry Mumber 727-21-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 7 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 727-21: (5*7)+(4*2)+(3*7)+(2*2)+(1*1)=69 69 % 10 = 9 So 727-21-9 is a valid CAS Registry Number.
