Check Digit Verification of cas no

The CAS Registry Mumber 850190-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,1,9 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 850190-71:
(8*8)+(7*5)+(6*0)+(5*1)+(4*9)+(3*0)+(2*7)+(1*1)=155
155 % 10 = 5
So 850190-71-5 is a valid CAS Registry Number.
