The CAS Registry Mumber 1589488-85-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,9,4,8 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1589488-85:
(9*1)+(8*5)+(7*8)+(6*9)+(5*4)+(4*8)+(3*8)+(2*8)+(1*5)=256
256 % 10 = 6
So 1589488-85-6 is a valid CAS Registry Number.
