Check Digit Verification of cas no

The CAS Registry Mumber 1233720-13-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1233720-13:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*2)+(3*0)+(2*1)+(1*3)=112
112 % 10 = 2
So 1233720-13-2 is a valid CAS Registry Number.
