Check Digit Verification of cas no

The CAS Registry Mumber 2166-95-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2166-95:
(6*2)+(5*1)+(4*6)+(3*6)+(2*9)+(1*5)=82
82 % 10 = 2
So 2166-95-2 is a valid CAS Registry Number.
