Check Digit Verification of cas no

The CAS Registry Mumber 904679-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,7 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 904679-53:
(8*9)+(7*0)+(6*4)+(5*6)+(4*7)+(3*9)+(2*5)+(1*3)=194
194 % 10 = 4
So 904679-53-4 is a valid CAS Registry Number.
