Check Digit Verification of cas no

The CAS Registry Mumber 791809-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,1,8,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 791809-99:
(8*7)+(7*9)+(6*1)+(5*8)+(4*0)+(3*9)+(2*9)+(1*9)=219
219 % 10 = 9
So 791809-99-9 is a valid CAS Registry Number.
