Check Digit Verification of cas no

The CAS Registry Mumber 16176-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16176-26:
(7*1)+(6*6)+(5*1)+(4*7)+(3*6)+(2*2)+(1*6)=104
104 % 10 = 4
So 16176-26-4 is a valid CAS Registry Number.
