Check Digit Verification of cas no

The CAS Registry Mumber 142133-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142133-31:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*3)+(2*3)+(1*1)=81
81 % 10 = 1
So 142133-31-1 is a valid CAS Registry Number.
