The CAS Registry Mumber 1634-60-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 4 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1634-60: (6*1)+(5*6)+(4*3)+(3*4)+(2*6)+(1*0)=72 72 % 10 = 2 So 1634-60-2 is a valid CAS Registry Number.
