Check Digit Verification of cas no

The CAS Registry Mumber 1333222-72-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,2 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1333222-72:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*2)+(3*2)+(2*7)+(1*2)=112
112 % 10 = 2
So 1333222-72-2 is a valid CAS Registry Number.
