Check Digit Verification of cas no

The CAS Registry Mumber 2821-13-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,2 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2821-13:
(6*2)+(5*8)+(4*2)+(3*1)+(2*1)+(1*3)=68
68 % 10 = 8
So 2821-13-8 is a valid CAS Registry Number.
