The CAS Registry Mumber 1013-12-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,1 and 3 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1013-12: (6*1)+(5*0)+(4*1)+(3*3)+(2*1)+(1*2)=23 23 % 10 = 3 So 1013-12-3 is a valid CAS Registry Number.
