Check Digit Verification of cas no

The CAS Registry Mumber 1065193-61-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,5,1,9 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1065193-61:
(9*1)+(8*0)+(7*6)+(6*5)+(5*1)+(4*9)+(3*3)+(2*6)+(1*1)=144
144 % 10 = 4
So 1065193-61-4 is a valid CAS Registry Number.
