The CAS Registry Mumber 87319-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,1 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87319-80:
(7*8)+(6*7)+(5*3)+(4*1)+(3*9)+(2*8)+(1*0)=160
160 % 10 = 0
So 87319-80-0 is a valid CAS Registry Number.
