Check Digit Verification of cas no

The CAS Registry Mumber 6398-69-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,9 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6398-69:
(6*6)+(5*3)+(4*9)+(3*8)+(2*6)+(1*9)=132
132 % 10 = 2
So 6398-69-2 is a valid CAS Registry Number.
