Check Digit Verification of cas no

The CAS Registry Mumber 109917-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,1 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109917-52:
(8*1)+(7*0)+(6*9)+(5*9)+(4*1)+(3*7)+(2*5)+(1*2)=144
144 % 10 = 4
So 109917-52-4 is a valid CAS Registry Number.
