Check Digit Verification of cas no

The CAS Registry Mumber 133490-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,9 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133490-56:
(8*1)+(7*3)+(6*3)+(5*4)+(4*9)+(3*0)+(2*5)+(1*6)=119
119 % 10 = 9
So 133490-56-9 is a valid CAS Registry Number.
