The CAS Registry Mumber 6539-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6539-67:
(6*6)+(5*5)+(4*3)+(3*9)+(2*6)+(1*7)=119
119 % 10 = 9
So 6539-67-9 is a valid CAS Registry Number.
