The CAS Registry Mumber 315-51-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 5 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 315-51: (5*3)+(4*1)+(3*5)+(2*5)+(1*1)=45 45 % 10 = 5 So 315-51-5 is a valid CAS Registry Number.
