Check Digit Verification of cas no

The CAS Registry Mumber 1022138-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,2,1,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1022138-65:
(9*1)+(8*0)+(7*2)+(6*2)+(5*1)+(4*3)+(3*8)+(2*6)+(1*5)=93
93 % 10 = 3
So 1022138-65-3 is a valid CAS Registry Number.
