Check Digit Verification of cas no

The CAS Registry Mumber 216302-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,3,0 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 216302-09:
(8*2)+(7*1)+(6*6)+(5*3)+(4*0)+(3*2)+(2*0)+(1*9)=89
89 % 10 = 9
So 216302-09-9 is a valid CAS Registry Number.
