Check Digit Verification of cas no

The CAS Registry Mumber 80819-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,1 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80819-63:
(7*8)+(6*0)+(5*8)+(4*1)+(3*9)+(2*6)+(1*3)=142
142 % 10 = 2
So 80819-63-2 is a valid CAS Registry Number.
