Check Digit Verification of cas no

The CAS Registry Mumber 220329-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,2 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 220329-92:
(8*2)+(7*2)+(6*0)+(5*3)+(4*2)+(3*9)+(2*9)+(1*2)=100
100 % 10 = 0
So 220329-92-0 is a valid CAS Registry Number.
