Check Digit Verification of cas no

The CAS Registry Mumber 144279-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,7 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144279-38:
(8*1)+(7*4)+(6*4)+(5*2)+(4*7)+(3*9)+(2*3)+(1*8)=139
139 % 10 = 9
So 144279-38-9 is a valid CAS Registry Number.
