Check Digit Verification of cas no

The CAS Registry Mumber 142599-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,9 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142599-82:
(8*1)+(7*4)+(6*2)+(5*5)+(4*9)+(3*9)+(2*8)+(1*2)=154
154 % 10 = 4
So 142599-82-4 is a valid CAS Registry Number.
