Check Digit Verification of cas no

The CAS Registry Mumber 129873-36-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,7 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129873-36:
(8*1)+(7*2)+(6*9)+(5*8)+(4*7)+(3*3)+(2*3)+(1*6)=165
165 % 10 = 5
So 129873-36-5 is a valid CAS Registry Number.
