Check Digit Verification of cas no

The CAS Registry Mumber 74268-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,6 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74268-63:
(7*7)+(6*4)+(5*2)+(4*6)+(3*8)+(2*6)+(1*3)=146
146 % 10 = 6
So 74268-63-6 is a valid CAS Registry Number.
