Check Digit Verification of cas no

The CAS Registry Mumber 316808-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,6,8,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 316808-40:
(8*3)+(7*1)+(6*6)+(5*8)+(4*0)+(3*8)+(2*4)+(1*0)=139
139 % 10 = 9
So 316808-40-9 is a valid CAS Registry Number.
