Check Digit Verification of cas no

The CAS Registry Mumber 6546-67-4 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 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6546-67:
(6*6)+(5*5)+(4*4)+(3*6)+(2*6)+(1*7)=114
114 % 10 = 4
So 6546-67-4 is a valid CAS Registry Number.
