The CAS Registry Mumber 1078-73-5 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, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1078-73: (6*1)+(5*0)+(4*7)+(3*8)+(2*7)+(1*3)=75 75 % 10 = 5 So 1078-73-5 is a valid CAS Registry Number.
