Check Digit Verification of cas no

The CAS Registry Mumber 352196-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,1,9 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 352196-29:
(8*3)+(7*5)+(6*2)+(5*1)+(4*9)+(3*6)+(2*2)+(1*9)=143
143 % 10 = 3
So 352196-29-3 is a valid CAS Registry Number.
