Check Digit Verification of cas no

The CAS Registry Mumber 140665-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140665-81:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*5)+(2*8)+(1*1)=122
122 % 10 = 2
So 140665-81-2 is a valid CAS Registry Number.
