Check Digit Verification of cas no

The CAS Registry Mumber 85543-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,4 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85543-66:
(7*8)+(6*5)+(5*5)+(4*4)+(3*3)+(2*6)+(1*6)=154
154 % 10 = 4
So 85543-66-4 is a valid CAS Registry Number.
