Check Digit Verification of cas no

The CAS Registry Mumber 2082-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2082-77:
(6*2)+(5*0)+(4*8)+(3*2)+(2*7)+(1*7)=71
71 % 10 = 1
So 2082-77-1 is a valid CAS Registry Number.
