Check Digit Verification of cas no

The CAS Registry Mumber 131318-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,1 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131318-38:
(8*1)+(7*3)+(6*1)+(5*3)+(4*1)+(3*8)+(2*3)+(1*8)=92
92 % 10 = 2
So 131318-38-2 is a valid CAS Registry Number.
