The CAS Registry Mumber 6470-98-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6470-98:
(6*6)+(5*4)+(4*7)+(3*0)+(2*9)+(1*8)=110
110 % 10 = 0
So 6470-98-0 is a valid CAS Registry Number.
