The CAS Registry Mumber 2005-58-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2005-58: (6*2)+(5*0)+(4*0)+(3*5)+(2*5)+(1*8)=45 45 % 10 = 5 So 2005-58-5 is a valid CAS Registry Number.
