Check Digit Verification of cas no

The CAS Registry Mumber 642949-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,9,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 642949-66:
(8*6)+(7*4)+(6*2)+(5*9)+(4*4)+(3*9)+(2*6)+(1*6)=194
194 % 10 = 4
So 642949-66-4 is a valid CAS Registry Number.
