Check Digit Verification of cas no

The CAS Registry Mumber 1268883-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,8 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1268883-53:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*8)+(3*3)+(2*5)+(1*3)=209
209 % 10 = 9
So 1268883-53-9 is a valid CAS Registry Number.
