Check Digit Verification of cas no

The CAS Registry Mumber 1254083-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,8 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254083-99:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*8)+(3*3)+(2*9)+(1*9)=152
152 % 10 = 2
So 1254083-99-2 is a valid CAS Registry Number.
