Check Digit Verification of cas no

The CAS Registry Mumber 109735-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,3 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109735-69:
(8*1)+(7*0)+(6*9)+(5*7)+(4*3)+(3*5)+(2*6)+(1*9)=145
145 % 10 = 5
So 109735-69-5 is a valid CAS Registry Number.
