Check Digit Verification of cas no

The CAS Registry Mumber 943253-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,2,5 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 943253-13:
(8*9)+(7*4)+(6*3)+(5*2)+(4*5)+(3*3)+(2*1)+(1*3)=162
162 % 10 = 2
So 943253-13-2 is a valid CAS Registry Number.
