Check Digit Verification of cas no

The CAS Registry Mumber 117438-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,3 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117438-35:
(8*1)+(7*1)+(6*7)+(5*4)+(4*3)+(3*8)+(2*3)+(1*5)=124
124 % 10 = 4
So 117438-35-4 is a valid CAS Registry Number.
