Check Digit Verification of cas no

The CAS Registry Mumber 219920-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219920-69:
(8*2)+(7*1)+(6*9)+(5*9)+(4*2)+(3*0)+(2*6)+(1*9)=151
151 % 10 = 1
So 219920-69-1 is a valid CAS Registry Number.
