Check Digit Verification of cas no

The CAS Registry Mumber 2811-28-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2811-28:
(6*2)+(5*8)+(4*1)+(3*1)+(2*2)+(1*8)=71
71 % 10 = 1
So 2811-28-1 is a valid CAS Registry Number.
