The CAS Registry Mumber 6503-26-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 3 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6503-26: (6*6)+(5*5)+(4*0)+(3*3)+(2*2)+(1*6)=80 80 % 10 = 0 So 6503-26-0 is a valid CAS Registry Number.
