Check Digit Verification of cas no

The CAS Registry Mumber 6473-12-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6473-12:
(6*6)+(5*4)+(4*7)+(3*3)+(2*1)+(1*2)=97
97 % 10 = 7
So 6473-12-7 is a valid CAS Registry Number.
