Check Digit Verification of cas no

The CAS Registry Mumber 264147-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,1,4 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 264147-43:
(8*2)+(7*6)+(6*4)+(5*1)+(4*4)+(3*7)+(2*4)+(1*3)=135
135 % 10 = 5
So 264147-43-5 is a valid CAS Registry Number.
