The CAS Registry Mumber 935-11-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 5 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 935-11: (5*9)+(4*3)+(3*5)+(2*1)+(1*1)=75 75 % 10 = 5 So 935-11-5 is a valid CAS Registry Number.
