Check Digit Verification of cas no

The CAS Registry Mumber 1127435-66-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,7,4,3 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1127435-66:
(9*1)+(8*1)+(7*2)+(6*7)+(5*4)+(4*3)+(3*5)+(2*6)+(1*6)=138
138 % 10 = 8
So 1127435-66-8 is a valid CAS Registry Number.
