Check Digit Verification of cas no

The CAS Registry Mumber 181767-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,7,6 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 181767-54:
(8*1)+(7*8)+(6*1)+(5*7)+(4*6)+(3*7)+(2*5)+(1*4)=164
164 % 10 = 4
So 181767-54-4 is a valid CAS Registry Number.
