Check Digit Verification of cas no

The CAS Registry Mumber 142941-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,4 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142941-68:
(8*1)+(7*4)+(6*2)+(5*9)+(4*4)+(3*1)+(2*6)+(1*8)=132
132 % 10 = 2
So 142941-68-2 is a valid CAS Registry Number.
