The CAS Registry Mumber 2483-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 3 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2483-32: (6*2)+(5*4)+(4*8)+(3*3)+(2*3)+(1*2)=81 81 % 10 = 1 So 2483-32-1 is a valid CAS Registry Number.
