Check Digit Verification of cas no

The CAS Registry Mumber 340154-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,1,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 340154-83:
(8*3)+(7*4)+(6*0)+(5*1)+(4*5)+(3*4)+(2*8)+(1*3)=108
108 % 10 = 8
So 340154-83-8 is a valid CAS Registry Number.
