Check Digit Verification of cas no

The CAS Registry Mumber 117917-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117917-99:
(8*1)+(7*1)+(6*7)+(5*9)+(4*1)+(3*7)+(2*9)+(1*9)=154
154 % 10 = 4
So 117917-99-4 is a valid CAS Registry Number.
