Check Digit Verification of cas no

The CAS Registry Mumber 138408-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,0 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138408-27:
(8*1)+(7*3)+(6*8)+(5*4)+(4*0)+(3*8)+(2*2)+(1*7)=132
132 % 10 = 2
So 138408-27-2 is a valid CAS Registry Number.
