The CAS Registry Mumber 100513-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,5,1 and 3 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 100513-53: (8*1)+(7*0)+(6*0)+(5*5)+(4*1)+(3*3)+(2*5)+(1*3)=59 59 % 10 = 9 So 100513-53-9 is a valid CAS Registry Number.
