Check Digit Verification of cas no

The CAS Registry Mumber 1342-85-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1342-85:
(6*1)+(5*3)+(4*4)+(3*2)+(2*8)+(1*5)=64
64 % 10 = 4
So 1342-85-4 is a valid CAS Registry Number.
