Check Digit Verification of cas no

The CAS Registry Mumber 220779-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,7,7 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220779-91:
(8*2)+(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*9)+(1*1)=139
139 % 10 = 9
So 220779-91-9 is a valid CAS Registry Number.
