Check Digit Verification of cas no

The CAS Registry Mumber 473932-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,9,3 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 473932-31:
(8*4)+(7*7)+(6*3)+(5*9)+(4*3)+(3*2)+(2*3)+(1*1)=169
169 % 10 = 9
So 473932-31-9 is a valid CAS Registry Number.
