Check Digit Verification of cas no

The CAS Registry Mumber 221302-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,0 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221302-02:
(8*2)+(7*2)+(6*1)+(5*3)+(4*0)+(3*2)+(2*0)+(1*2)=59
59 % 10 = 9
So 221302-02-9 is a valid CAS Registry Number.
