Check Digit Verification of cas no

The CAS Registry Mumber 1228343-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228343-89:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*4)+(3*3)+(2*8)+(1*9)=152
152 % 10 = 2
So 1228343-89-2 is a valid CAS Registry Number.
