The CAS Registry Mumber 1078-13-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1078-13: (6*1)+(5*0)+(4*7)+(3*8)+(2*1)+(1*3)=63 63 % 10 = 3 So 1078-13-3 is a valid CAS Registry Number.
