Check Digit Verification of cas no

The CAS Registry Mumber 40665-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,6 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40665-86:
(7*4)+(6*0)+(5*6)+(4*6)+(3*5)+(2*8)+(1*6)=119
119 % 10 = 9
So 40665-86-9 is a valid CAS Registry Number.
