Check Digit Verification of cas no

The CAS Registry Mumber 217805-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,8,0 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 217805-59:
(8*2)+(7*1)+(6*7)+(5*8)+(4*0)+(3*5)+(2*5)+(1*9)=139
139 % 10 = 9
So 217805-59-9 is a valid CAS Registry Number.
