Check Digit Verification of cas no

The CAS Registry Mumber 133672-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,7 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133672-90:
(8*1)+(7*3)+(6*3)+(5*6)+(4*7)+(3*2)+(2*9)+(1*0)=129
129 % 10 = 9
So 133672-90-9 is a valid CAS Registry Number.
