Check Digit Verification of cas no

The CAS Registry Mumber 1164251-82-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,4,2,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1164251-82:
(9*1)+(8*1)+(7*6)+(6*4)+(5*2)+(4*5)+(3*1)+(2*8)+(1*2)=134
134 % 10 = 4
So 1164251-82-4 is a valid CAS Registry Number.
