Check Digit Verification of cas no

The CAS Registry Mumber 144571-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144571-74:
(8*1)+(7*4)+(6*4)+(5*5)+(4*7)+(3*1)+(2*7)+(1*4)=134
134 % 10 = 4
So 144571-74-4 is a valid CAS Registry Number.
