Check Digit Verification of cas no

The CAS Registry Mumber 1676-11-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1676-11:
(6*1)+(5*6)+(4*7)+(3*6)+(2*1)+(1*1)=85
85 % 10 = 5
So 1676-11-5 is a valid CAS Registry Number.
