Check Digit Verification of cas no

The CAS Registry Mumber 862206-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,2,0 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 862206-31:
(8*8)+(7*6)+(6*2)+(5*2)+(4*0)+(3*6)+(2*3)+(1*1)=153
153 % 10 = 3
So 862206-31-3 is a valid CAS Registry Number.
