Check Digit Verification of cas no

The CAS Registry Mumber 93711-86-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,1 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93711-86:
(7*9)+(6*3)+(5*7)+(4*1)+(3*1)+(2*8)+(1*6)=145
145 % 10 = 5
So 93711-86-5 is a valid CAS Registry Number.
