Check Digit Verification of cas no

The CAS Registry Mumber 957255-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,2,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 957255-22:
(8*9)+(7*5)+(6*7)+(5*2)+(4*5)+(3*5)+(2*2)+(1*2)=200
200 % 10 = 0
So 957255-22-0 is a valid CAS Registry Number.
