Check Digit Verification of cas no

The CAS Registry Mumber 81910-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,1 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81910-71:
(7*8)+(6*1)+(5*9)+(4*1)+(3*0)+(2*7)+(1*1)=126
126 % 10 = 6
So 81910-71-6 is a valid CAS Registry Number.
