Check Digit Verification of cas no

The CAS Registry Mumber 326476-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,6,4,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 326476-83:
(8*3)+(7*2)+(6*6)+(5*4)+(4*7)+(3*6)+(2*8)+(1*3)=159
159 % 10 = 9
So 326476-83-9 is a valid CAS Registry Number.
