Check Digit Verification of cas no

The CAS Registry Mumber 216433-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,4,3 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 216433-17:
(8*2)+(7*1)+(6*6)+(5*4)+(4*3)+(3*3)+(2*1)+(1*7)=109
109 % 10 = 9
So 216433-17-9 is a valid CAS Registry Number.
