Check Digit Verification of cas no

The CAS Registry Mumber 3452-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3452-91:
(6*3)+(5*4)+(4*5)+(3*2)+(2*9)+(1*1)=83
83 % 10 = 3
So 3452-91-3 is a valid CAS Registry Number.
