Check Digit Verification of cas no

The CAS Registry Mumber 143212-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,1 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143212-41:
(8*1)+(7*4)+(6*3)+(5*2)+(4*1)+(3*2)+(2*4)+(1*1)=83
83 % 10 = 3
So 143212-41-3 is a valid CAS Registry Number.
