Check Digit Verification of cas no

The CAS Registry Mumber 140241-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,4 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140241-67:
(8*1)+(7*4)+(6*0)+(5*2)+(4*4)+(3*1)+(2*6)+(1*7)=84
84 % 10 = 4
So 140241-67-4 is a valid CAS Registry Number.
