Check Digit Verification of cas no

The CAS Registry Mumber 347840-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,8,4 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 347840-59:
(8*3)+(7*4)+(6*7)+(5*8)+(4*4)+(3*0)+(2*5)+(1*9)=169
169 % 10 = 9
So 347840-59-9 is a valid CAS Registry Number.
