Check Digit Verification of cas no

The CAS Registry Mumber 193481-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,8 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 193481-16:
(8*1)+(7*9)+(6*3)+(5*4)+(4*8)+(3*1)+(2*1)+(1*6)=152
152 % 10 = 2
So 193481-16-2 is a valid CAS Registry Number.
