Check Digit Verification of cas no

The CAS Registry Mumber 5460-76-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,6 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5460-76:
(6*5)+(5*4)+(4*6)+(3*0)+(2*7)+(1*6)=94
94 % 10 = 4
So 5460-76-4 is a valid CAS Registry Number.
