Check Digit Verification of cas no

The CAS Registry Mumber 157380-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,3,8 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157380-24:
(8*1)+(7*5)+(6*7)+(5*3)+(4*8)+(3*0)+(2*2)+(1*4)=140
140 % 10 = 0
So 157380-24-0 is a valid CAS Registry Number.
