Check Digit Verification of cas no

The CAS Registry Mumber 157394-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,3,9 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157394-81:
(8*1)+(7*5)+(6*7)+(5*3)+(4*9)+(3*4)+(2*8)+(1*1)=165
165 % 10 = 5
So 157394-81-5 is a valid CAS Registry Number.
