Check Digit Verification of cas no

The CAS Registry Mumber 352443-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,4,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 352443-99:
(8*3)+(7*5)+(6*2)+(5*4)+(4*4)+(3*3)+(2*9)+(1*9)=143
143 % 10 = 3
So 352443-99-3 is a valid CAS Registry Number.
