The CAS Registry Mumber 6460-41-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 0 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6460-41: (6*6)+(5*4)+(4*6)+(3*0)+(2*4)+(1*1)=89 89 % 10 = 9 So 6460-41-9 is a valid CAS Registry Number.
