Check Digit Verification of cas no

The CAS Registry Mumber 329038-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,9,0,3 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 329038-46:
(8*3)+(7*2)+(6*9)+(5*0)+(4*3)+(3*8)+(2*4)+(1*6)=142
142 % 10 = 2
So 329038-46-2 is a valid CAS Registry Number.
