Check Digit Verification of cas no

The CAS Registry Mumber 925453-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,4,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 925453-22:
(8*9)+(7*2)+(6*5)+(5*4)+(4*5)+(3*3)+(2*2)+(1*2)=171
171 % 10 = 1
So 925453-22-1 is a valid CAS Registry Number.
