Check Digit Verification of cas no

The CAS Registry Mumber 945931-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,9,3 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 945931-96:
(8*9)+(7*4)+(6*5)+(5*9)+(4*3)+(3*1)+(2*9)+(1*6)=214
214 % 10 = 4
So 945931-96-4 is a valid CAS Registry Number.
