Check Digit Verification of cas no

The CAS Registry Mumber 76261-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,6 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76261-28:
(7*7)+(6*6)+(5*2)+(4*6)+(3*1)+(2*2)+(1*8)=134
134 % 10 = 4
So 76261-28-4 is a valid CAS Registry Number.
