Check Digit Verification of cas no

The CAS Registry Mumber 140664-96-6 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 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140664-96:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*4)+(2*9)+(1*6)=126
126 % 10 = 6
So 140664-96-6 is a valid CAS Registry Number.
