Check Digit Verification of cas no

The CAS Registry Mumber 1111657-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,6,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1111657-83:
(9*1)+(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*7)+(2*8)+(1*3)=120
120 % 10 = 0
So 1111657-83-0 is a valid CAS Registry Number.
