Check Digit Verification of cas no

The CAS Registry Mumber 311320-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,3,2 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 311320-41:
(8*3)+(7*1)+(6*1)+(5*3)+(4*2)+(3*0)+(2*4)+(1*1)=69
69 % 10 = 9
So 311320-41-9 is a valid CAS Registry Number.
