Check Digit Verification of cas no

The CAS Registry Mumber 152389-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,3,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 152389-45:
(8*1)+(7*5)+(6*2)+(5*3)+(4*8)+(3*9)+(2*4)+(1*5)=142
142 % 10 = 2
So 152389-45-2 is a valid CAS Registry Number.
