The CAS Registry Mumber 73232-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,3 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73232-50:
(7*7)+(6*3)+(5*2)+(4*3)+(3*2)+(2*5)+(1*0)=105
105 % 10 = 5
So 73232-50-5 is a valid CAS Registry Number.
