Check Digit Verification of cas no

The CAS Registry Mumber 219640-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,4 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 219640-22:
(8*2)+(7*1)+(6*9)+(5*6)+(4*4)+(3*0)+(2*2)+(1*2)=129
129 % 10 = 9
So 219640-22-9 is a valid CAS Registry Number.
