Check Digit Verification of cas no

The CAS Registry Mumber 478491-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,4,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 478491-22:
(8*4)+(7*7)+(6*8)+(5*4)+(4*9)+(3*1)+(2*2)+(1*2)=194
194 % 10 = 4
So 478491-22-4 is a valid CAS Registry Number.
