Check Digit Verification of cas no

The CAS Registry Mumber 6411-63-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6411-63:
(6*6)+(5*4)+(4*1)+(3*1)+(2*6)+(1*3)=78
78 % 10 = 8
So 6411-63-8 is a valid CAS Registry Number.
