The CAS Registry Mumber 13304-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,0 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13304-18:
(7*1)+(6*3)+(5*3)+(4*0)+(3*4)+(2*1)+(1*8)=62
62 % 10 = 2
So 13304-18-2 is a valid CAS Registry Number.
