The CAS Registry Mumber 104303-60-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,0 and 3 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 104303-60: (8*1)+(7*0)+(6*4)+(5*3)+(4*0)+(3*3)+(2*6)+(1*0)=68 68 % 10 = 8 So 104303-60-8 is a valid CAS Registry Number.
