Check Digit Verification of cas no

The CAS Registry Mumber 1026745-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,7,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1026745-65:
(9*1)+(8*0)+(7*2)+(6*6)+(5*7)+(4*4)+(3*5)+(2*6)+(1*5)=142
142 % 10 = 2
So 1026745-65-2 is a valid CAS Registry Number.
