Check Digit Verification of cas no

The CAS Registry Mumber 273381-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,3,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 273381-23:
(8*2)+(7*7)+(6*3)+(5*3)+(4*8)+(3*1)+(2*2)+(1*3)=140
140 % 10 = 0
So 273381-23-0 is a valid CAS Registry Number.
