Check Digit Verification of cas no

The CAS Registry Mumber 2259-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2259-11:
(6*2)+(5*2)+(4*5)+(3*9)+(2*1)+(1*1)=72
72 % 10 = 2
So 2259-11-2 is a valid CAS Registry Number.
