Check Digit Verification of cas no

The CAS Registry Mumber 82721-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82721-76:
(7*8)+(6*2)+(5*7)+(4*2)+(3*1)+(2*7)+(1*6)=134
134 % 10 = 4
So 82721-76-4 is a valid CAS Registry Number.
