Check Digit Verification of cas no

The CAS Registry Mumber 26166-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,6 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26166-55:
(7*2)+(6*6)+(5*1)+(4*6)+(3*6)+(2*5)+(1*5)=112
112 % 10 = 2
So 26166-55-2 is a valid CAS Registry Number.
