Check Digit Verification of cas no

The CAS Registry Mumber 866721-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,6,7,2 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 866721-93:
(8*8)+(7*6)+(6*6)+(5*7)+(4*2)+(3*1)+(2*9)+(1*3)=209
209 % 10 = 9
So 866721-93-9 is a valid CAS Registry Number.
