Check Digit Verification of cas no

The CAS Registry Mumber 676-43-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 676-43:
(5*6)+(4*7)+(3*6)+(2*4)+(1*3)=87
87 % 10 = 7
So 676-43-7 is a valid CAS Registry Number.
