Check Digit Verification of cas no

The CAS Registry Mumber 1421663-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1421663-83:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*6)+(3*3)+(2*8)+(1*3)=143
143 % 10 = 3
So 1421663-83-3 is a valid CAS Registry Number.
