The CAS Registry Mumber 1486-33-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 6 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1486-33: (6*1)+(5*4)+(4*8)+(3*6)+(2*3)+(1*3)=85 85 % 10 = 5 So 1486-33-5 is a valid CAS Registry Number.
