Check Digit Verification of cas no

The CAS Registry Mumber 134834-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,3 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134834-72:
(8*1)+(7*3)+(6*4)+(5*8)+(4*3)+(3*4)+(2*7)+(1*2)=133
133 % 10 = 3
So 134834-72-3 is a valid CAS Registry Number.
