Check Digit Verification of cas no

The CAS Registry Mumber 1649471-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,9,4,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1649471-91:
(9*1)+(8*6)+(7*4)+(6*9)+(5*4)+(4*7)+(3*1)+(2*9)+(1*1)=209
209 % 10 = 9
So 1649471-91-9 is a valid CAS Registry Number.
