Check Digit Verification of cas no

The CAS Registry Mumber 334917-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,9,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 334917-69:
(8*3)+(7*3)+(6*4)+(5*9)+(4*1)+(3*7)+(2*6)+(1*9)=160
160 % 10 = 0
So 334917-69-0 is a valid CAS Registry Number.
