Check Digit Verification of cas no

The CAS Registry Mumber 138067-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,6 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138067-74:
(8*1)+(7*3)+(6*8)+(5*0)+(4*6)+(3*7)+(2*7)+(1*4)=140
140 % 10 = 0
So 138067-74-0 is a valid CAS Registry Number.
