Check Digit Verification of cas no

The CAS Registry Mumber 225797-90-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,7,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 225797-90:
(8*2)+(7*2)+(6*5)+(5*7)+(4*9)+(3*7)+(2*9)+(1*0)=170
170 % 10 = 0
So 225797-90-0 is a valid CAS Registry Number.
