Check Digit Verification of cas no

The CAS Registry Mumber 1187209-55-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,2,0 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1187209-55:
(9*1)+(8*1)+(7*8)+(6*7)+(5*2)+(4*0)+(3*9)+(2*5)+(1*5)=167
167 % 10 = 7
So 1187209-55-7 is a valid CAS Registry Number.
