Check Digit Verification of cas no

The CAS Registry Mumber 6544-89-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6544-89:
(6*6)+(5*5)+(4*4)+(3*4)+(2*8)+(1*9)=114
114 % 10 = 4
So 6544-89-4 is a valid CAS Registry Number.
