Check Digit Verification of cas no

The CAS Registry Mumber 213321-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,3,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 213321-21:
(8*2)+(7*1)+(6*3)+(5*3)+(4*2)+(3*1)+(2*2)+(1*1)=72
72 % 10 = 2
So 213321-21-2 is a valid CAS Registry Number.
