Check Digit Verification of cas no

The CAS Registry Mumber 913369-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,3,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 913369-53:
(8*9)+(7*1)+(6*3)+(5*3)+(4*6)+(3*9)+(2*5)+(1*3)=176
176 % 10 = 6
So 913369-53-6 is a valid CAS Registry Number.
