Check Digit Verification of cas no

The CAS Registry Mumber 244240-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 244240-01:
(8*2)+(7*4)+(6*4)+(5*2)+(4*4)+(3*0)+(2*0)+(1*1)=95
95 % 10 = 5
So 244240-01-5 is a valid CAS Registry Number.
