Check Digit Verification of cas no

The CAS Registry Mumber 140901-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,0 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140901-61:
(8*1)+(7*4)+(6*0)+(5*9)+(4*0)+(3*1)+(2*6)+(1*1)=97
97 % 10 = 7
So 140901-61-7 is a valid CAS Registry Number.
