Check Digit Verification of cas no

The CAS Registry Mumber 1640-52-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1640-52:
(6*1)+(5*6)+(4*4)+(3*0)+(2*5)+(1*2)=64
64 % 10 = 4
So 1640-52-4 is a valid CAS Registry Number.
