The CAS Registry Mumber 4055-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 5 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4055-06: (6*4)+(5*0)+(4*5)+(3*5)+(2*0)+(1*6)=65 65 % 10 = 5 So 4055-06-5 is a valid CAS Registry Number.
