Check Digit Verification of cas no

The CAS Registry Mumber 6542-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6542-34:
(6*6)+(5*5)+(4*4)+(3*2)+(2*3)+(1*4)=93
93 % 10 = 3
So 6542-34-3 is a valid CAS Registry Number.
