Check Digit Verification of cas no

The CAS Registry Mumber 135923-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135923-09:
(8*1)+(7*3)+(6*5)+(5*9)+(4*2)+(3*3)+(2*0)+(1*9)=130
130 % 10 = 0
So 135923-09-0 is a valid CAS Registry Number.
