The CAS Registry Mumber 4103-68-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4103-68: (6*4)+(5*1)+(4*0)+(3*3)+(2*6)+(1*8)=58 58 % 10 = 8 So 4103-68-8 is a valid CAS Registry Number.
